Claw Clip Manufacturer’s Perspective: Detailed Explanation of the Acetate Claw Clip Manufacturing Process

Have you ever been captivated by the glossy finish of acetate claw clips? Are you curious about how an acetate claw clip is made? If you want to know the answers and unveil the mysteries of high-end acetate claw clip production, then follow along as I, from the perspective of a claw clip manufacturer, detail each stage and process of acetate claw clip manufacturing.

1. What are the main stages and processes in manufacturing acetate claw clips?

From a simple design drawing to a high-quality acetate claw clip, it may seem simple, but in reality, it involves more than a dozen stages and processes, mainly including 10 basic stages and three additional processes:

10 basic stages： (1) Communicating the claw clip design (2) Selecting the acetate board color and pattern (3) CNC machine cutting the acetate board (4) Polishing the claw clip pieces (5) Hot pressing (6) Adhesive spring slot (7) Spray painting (8) Installing springs (9) Product quality inspection (10) Packaging

3 additional processes: (1) Claw clip splicing process, (2) Surface decoration process, (3) Logo making process

2. Step 1: Communicating the claw clip design

In the claw clip design stage, if you find a professional claw clip manufacturer, you can simply provide a sketch of the claw clip design and the core parameters. The professional claw clip manufacturer will provide a feasible rendering based on your sketch. The specific core parameters include:

Parameter	Description	Notes
Size	Length, width, height, claw length	Longer clips = higher material cost; very short claws = weak grip
Tooth type	Glue-bonded teeth / molded teeth	Bonded: flexible design but slightly less durable; Molded: stronger but limited shapes
Tooth spacing	Distance between teeth	Affects grip strength & hair volume compatibility
Opening angle	Maximum opening angle	Too large → spring wears out faster; Too small → limited grip
Sheet thickness	2–8 mm acetate sheets	Too thin → breaks easily; Too thick → heavy and costly
Weight	Finished claw clip weight	Premium brands: 20–35 g; lightweight: 15–20 g
Logo & custom elements	Process, size, color, placement	Complex logos increase cost

Through communication and consensus on specific core parameters, the prototype of your claw clip design will be fully presented through renderings, accurately reflecting your claw clip design and laying a solid foundation for the entire claw clip manufacturing process.

3. Step 2: Choosing the Acetate Board Color and Pattern

An eye-catching acetate claw clip is inseparable from the choice of acetate board color and pattern. The color and pattern of the acetate board directly determine the visual effect of the claw clip. Common acetate board colors and patterns include:

Color/Pattern Type	Features	Application
Transparent	Pure, light-passing	Luxury minimalist styles
Solid color	Even pigmentation	Fast-fashion, basic series
Gradient	Smooth tonal transition	Premium custom designs
Tortoiseshell / Agate	Natural, classic look	High-end US/EU/Japan markets
Shell/Pearl texture	Soft, natural luster	Luxury hair accessories
Ice pattern / Marble	Random, unique texture	Customized limited editions

You can communicate your desired color to the claw clip manufacturer based on the claw clip design. They will provide corresponding color cards or sample books according to your needs. In addition, the claw clip manufacturer will also provide further suggestions based on your design and target market. After both parties confirm the color and pattern of the acetate, the manufacturer will purchase acetate sheets based on your acetate claw clips’ color, pattern, quantity, size, and other parameters. When choosing the color and pattern of the acetate, you need to know:

• Acetate cutting loss: There will be a 5-15% loss when cutting acetate sheets.
• Sheet thickness and color matching: Different thicknesses of the same color will have different visual effects; thicker, darker sheets have a stronger gloss; thicker, lighter sheets are more transparent.
• Archive the original acetate color: Keep photos of the original acetate color and texture as a basis for comparison in subsequent batches to avoid color deviations in later batches.
• Target market preferences: The European and American markets prefer natural textures, tortoiseshell, and ice-patterned patterns; the Japanese/Korean markets prefer elegant colors and light color gradients; high-end custom brands require symmetrical textures and uniform colors.

4. Step 3: CNC Machine Cutting of Acetate Board

Before the CNC engraving machine officially cuts the acetate board, the claw clip manufacturer needs to draw a vector outline based on the customer’s design. The CNC engraving machine needs to cut according to this vector outline drawing, which must clearly define:

• Outline
• Claw clip tooth position and spacing
• Hole positions (spring mounting holes, logo mounting holes)
• Thickened or thinned areas (e.g., thickness variations)

After finalizing the outline drawing, the acetate board needs to be securely fixed to the CNC worktable to prevent movement during cutting, which could cause edge burrs or dimensional deviations. Then, a suitable cutting tool is selected, which must match the claw clip design and dimensions. Finally, the CNC engraving machine parameters are set according to the claw clip design.

After completing the CNC cutting, the claw clip manufacturer needs to conduct a comprehensive inspection of the claw clip’s dimensions, claw clip tooth integrity, and hole position accuracy to ensure consistency in subsequent batch cutting.

5. Step 4: Polishing the Claw Clip Plates

After the CNC engraving machine cuts the claw clip pieces, although the shape is precise, the freshly cut claw clip pieces are not smooth overall. This is mainly due to: burrs on the edges, scratches from the cuts, a rough surface, and an uneven texture. Therefore, these claw clip pieces

need to be polished to achieve a high-end and glossy visual effect. The polishing process is as follows:

• Place the CNC-cut claw clip pieces into a tumbling machine.
• Add tumbling media such as wood chips, plastic granules, resin granules, or abrasives into the tumbling drum.
• Through the rotational friction of the drum, the surface of the claw clip pieces is initially smoothed and flattened.

Through mechanical tumbling polishing, burrs and scratches on the surface of the claw clip pieces

can be efficiently removed, achieving a uniform and rounded effect.

During the polishing process, the hair clip manufacturer is not completely uninvolved. We need to control the drum’s working time. If the drum time is too short, burrs may not be completely removed; if the drum time is too long, the surface may be slightly worn, and the texture may become blurred. In addition, the media inside the drum must be matched to the hardness of the material to avoid scratching the material.

6. Step 5: Hot Pressing

After completing the CNC cutting, polishing, and assembly, the claw clip pieces are still only flat. To transform them into a three-dimensional, gripping structure, hot pressing is needed to fix the claw’s curvature. Before starting the hot pressing process, claw clip manufacturers utilize the following equipment:

• Mold: A mold customized according to the claw clip design or model, consisting of upper and lower molds. The lower mold has claw clip tooth positioning holes.
• Heating Equipment: Heats the single-color or multi-color clip pieces to soften the acetate claw clip pieces.
• Press Machine: Applies pressure to the softened acetate claw clip pieces fixed in the mold to shape them.

Specific Process:

• Preheating the Clip Pieces: Preheat the single-color or multi-color claw clip pieces in the heating equipment for 10-15 seconds.
• Placing the Claw Clip Pieces: Fix the softened claw clip pieces in the mold, ensuring the pattern orientation is correct.
• Pressing with the Press Machine: Apply pressure and press for 5-10 seconds to bend the claw clip pieces into shape.
• Cooling and Shaping: Remove the bent claw clip pieces from the press and immerse them in cold water to cool naturally for 1-3 minutes to ensure the curvature is stable. After cooling, they are removed to form semi-finished claw clip pieces.

7. Step 6: Adhesive spring slot

In acetate claw clip structures, a groove or fixing slot, called a spring slot, is typically designed into the claw clip body to ensure smooth operation of the metal spring and a secure connection between the two claw clip pieces. Compared to claw clips without spring slots, it allows for precise spring positioning, increases stability, improves durability, and optimizes the appearance.

Applying the spring slot involves aligning the left and right claw clip pieces, applying the spring slot to both sides with specialized adhesive, pressing and allowing it to cure for 10-15 seconds to ensure the final product is secure and does not shift.

8. Step 7: Painting

To improve the surface gloss of the acetate claw clips and create a more high-end brand image, the claw clip manufacturer needs to perform a comprehensive painting treatment on each acetate claw clip. The main steps of the painting process are:

• Cleaning the claw clip surface: Wipe the claw clip with anhydrous alcohol to remove dust, fingerprints, and oil stains, and then dry it with an anti-static air gun to prevent dust from adsorbing again.
• Applying primer: To improve paint adhesion on the claw clip surface, a layer of primer needs to be sprayed. After spraying the primer, allow it to air dry naturally for 5-10 minutes.
• Main color painting: Use a spray paint tool to evenly coat the claw clip from all sides.
• Initial drying: After the main color painting, the claw clip needs to be dried initially to cure the paint and improve adhesion. Dry for 15-30 minutes. However, the temperature should not be too high, otherwise deformation may occur.
• Topcoat Application: To protect the paint from the previous step, a second topcoat is applied to prevent peeling and enhance the texture.
• Second Drying: After the topcoat is applied, a second drying time of 30-60 minutes is required. After drying, the jaws will have a stable texture and will be less prone to paint peeling.
• Static Cooling: After drying, a second static cooling period of 3-12 hours is necessary to ensure a completely uniform paint film and improve wear resistance.

9. Step 8: Install spring

In the production of acetate claw clips, spring installation is a core step in structural assembly and a crucial process for ensuring stable elasticity, smooth opening and closing, and structural durability. The specific installation process is as follows:

• Install the spring: After the spring grooves on the claw clips have cured, insert the spring into the spring groove of one claw clip. Use a hollow tube to press the two ends of the spring onto the same line, then fasten the other claw clip.
• Insert the metal shaft: Directly insert the metal shaft into the shaft hole between the two spring grooves. The toothed structure of the metal shaft and the spring force will directly lock the metal shaft in place, preventing it from being pulled out.
• Check the opening and closing feel: This mainly involves checking whether the claw clips open and close smoothly, whether the left and right claw clip teeth are aligned, and whether the clamping force is appropriate.

10. Step 9: Product Quality Inspection

After completing the above steps, the acetate claw clip has completed the production stage. To ensure that each acetate claw clip meets design and usage standards before leaving the factory, the manufacturer will conduct quality inspection on each claw clip. The main quality inspection items are:

• Appearance Inspection: Check for scratches, bubbles, and defects on the surface; check for crookedness of the logo, metal parts, and decorative parts.
• Functionality Inspection: Check whether the claw clip opens and closes smoothly, whether the spring clamping force is uniform, and whether the clamping teeth are aligned.
• Safety Inspection: Check whether the edges of the claw clip are sharp and whether there are burrs.
• Durability Inspection: Check whether the logo, paint, rhinestones, and steel balls are secure.

11. Step 10: Packaging

After confirming that the claw clip meets the factory standards, the manufacturer will package the claw clip to prevent scratches and damage during transportation.

Packaging can be divided into single-piece packaging, batch packaging, and outer carton packaging. Most manufacturers default to OPP bags/transparent PE bags for single-piece and bulk packaging, with corrugated cardboard boxes for outer packaging. This is suitable for B2B buyers who don’t care about outer packaging or will use secondary packaging.

Of course, if you have high requirements for packaging, you can request the claw clip manufacturer to customize the packaging according to your specifications, such as packaging form, color, and size.

12. Additional Processes

(1) Claw Clip Splicing Process

For simple, single-color claw clips, CNC cutting and polishing are usually sufficient for direct thermoforming. However, for multi-color, multi-textured, complex patterns, or custom-designed acetate claw clips, multiple polished claw clip pieces need to be assembled to form a complete and coherent pattern. The specific process is as follows:

• Sort the colors and textures according to the design drawing.
• Number each color/texture claw clip piece.
• Assemble the claw clip pieces according to the numbering order and angle, ensuring they fit tightly, align naturally, and appear natural.
• Apply special adhesive to the splicing edges, being careful to use an appropriate amount.
• Press the assembled claw clip pieces for 5-10 minutes to allow the adhesive to cure.
• After curing, check the surface for gaps, flatness, and smoothness. Repair any substandard products.

If your design involves an assembly process, this process must be completed before the polishing stage and after cutting the acetate board.

(2) Surface Decoration Process

Acetate claw clips are high-end hair accessories with a very eye-catching visual effect. To achieve this effect, the surface of the acetate claw clips needs to be decorated. The four main surface decoration processes are:

① Engraving and Painting Process

Engraving and painting involve carving grooves into the surface of the acetate board, then filling the grooves with colored paint to form patterns such as flowers, lines, geometric shapes, and logos. This is a high-end process combining manual and mechanical techniques. It can present a delicate, handmade texture and enhance the design’s sophistication. The process flow is as follows:

• Inspect the surface engraving: Use a CNC engraving machine to carve 0.1-0.3mm grooves on the claw clip surface.
• Clean the claw clip surface: Wipe the clip surface with alcohol and a lint-free cloth to remove oil and dust.
• Hand-paint the lines: Use an ultra-fine drawing pen dipped in environmentally friendly paint to evenly apply color along the grooves.
• Drying: Low-temperature curing of the pigments.

If your design involves engraving and painting, this process must be completed before the polishing stage and after cutting the acetate board.

② Rhinestone/Pearl Application

Rhinestone/pearl application involves attaching rhinestones, artificial pearls, and gemstone accessories of various sizes to the surface of the claw clip. This is done manually or with semi-automatic equipment. It produces a refined and elegant appearance. The process is as follows:

• Engraving Grooves: Using a CNC engraving machine, grooves with a depth of 0.1-0.3mm are engraved on the surface of the claw clip.
• Cleaning Grooves: The grooves on the claw clip surface are wiped with alcohol and a lint-free cloth to remove oil and dust.
• Applying Glue: Glue is applied to the grooves on the claw clip surface.
• Rhinestone/Pearl Application: Different-sized diamonds/pearls are placed into the grooves using tools.
• Curing Glue: After rhinestone/pearl application, it needs to cure naturally for 5-10 minutes to ensure that the rhinestones will not fall off later.

If your design involves rhinestone/pearl application, this process must be completed before the quality inspection stage and after the spring is installed.

③ Steel Ball Pressing Process

Steel ball pressing involves pressing small metal balls into an acetate substrate using a machine, making them firmly bonded to the surface. Compared to rhinestone application, it is more wear-resistant, drop-resistant, and will not fall off. Creating a light, luxurious, elegant, and retro style, the process flow is as follows:

• Engraving grooves: Using a CNC engraving machine, grooves with a depth of 0.1-0.3mm are engraved on the surface of the claw clip.
• Cleaning the grooves: Wipe the grooves on the surface of the claw clip with alcohol and a lint-free cloth to remove oil and dust.
• Placing steel balls: Place all steel balls in the grooves on the surface of the claw clip.
• Pressing the steel balls: Use a ball pressing machine to press the steel balls into the grooves.

If your design involves a steel ball pressing process, this process must be completed before the hot pressing stage and after polishing.

④ UV Printing

UV printing involves directly printing digital patterns onto the surface and then curing them with UV light, resulting in high saturation and gloss. Printable designs include: logos, cartoon patterns, gradients, and designs. It can achieve complex patterns, bright colors, and colorfastness. Process Flow:

• Pattern Design: Prepare printing files
• Apply base coat (depending on the situation)
• UV Printing: Print directly on the surface using a UV printer
• UV Curing: The ink layer is quickly cured by light irradiation
• Surface Treatment (Matte/Gloss optional)

If your design involves UV printing, this process must be completed before the thermoforming stage and after polishing.

(3) Logo Production Process

To ensure a higher level of brand recognition on acetate hair accessories, we offer a variety of professional logo processing methods, including printing, engraving, and inlay/adhesive, to meet different brand styles and customization needs.

① Printing (UV Printing, Pad Printing)

• UV Printing: Directly print colored patterns on the acetate surface. The patterns adhere smoothly, and the surface has a glossy feel. Gradient, colored logos, or complex patterns can be printed. Advantages include bright colors, smooth surface, and delicate patterns.
• Pad Printing: A silicone printhead transfers a single-color or two-color logo onto the surface. Suitable for small areas or text-based logos. Advantages include clear lines, a distinct single color, and a slightly raised feel. This process must be completed before the thermoforming stage and after polishing.

② Engraving (Engraved/Unpainted)

• Engraved/Painted: The logo outline is engraved into the acetate surface, then filled with paint by hand to create a three-dimensional color pattern. Advantages include a distinct three-dimensional effect, rich colors, and a refined, high-end look.
• Engraved/Unpainted: The logo is engraved on the surface without painting, creating a monochromatic engraving effect. Advantages include understated elegance, suitable for minimalist or high-end styles.

③ Inlay/Adhesive (Rhinestones/Pearls, Steel Beads)

• Rhinestones/Pearls: Small rhinestones or artificial pearls are glued to the surface of the hair accessory to form a logo or decorative pattern. Advantages include a shiny, delicate appearance and a three-dimensional pattern.
• Pressed Steel Beads: Small metal beads are pressed and riveted to the surface of the hair accessory, forming a raised logo or decoration. Advantages include raised metal beads, durability, and a metallic feel.
• Adhesive Metal Labels: Custom metal labels or logos are fixed to the surface of acetate hair accessories or clips using high-strength adhesive. This adds texture and durability. This process must be completed before quality inspection and after spring installation.

④ Common Logo Production Process:

• Choosing a Logo Process: Select a suitable production method based on materials, production costs, and brand positioning.
• Determining Logo Size and Position: The logo size should not be too large or too small, and the font should not be too thin. Common positions include the inner, outer, and side edges. Professional manufacturers will provide relevant suggestions and proportion diagrams based on your needs.
• Inspection: After the logo is completed, it needs to be checked to ensure it is flat and not crooked.

Every detail of acetate claw clips, from initial communication to polishing, splicing, quality inspection, and packaging, directly affects the final product quality and brand image. Therefore, for B2B buyers seeking long-term cooperation, choosing a claw clip manufacturer with full-process customization capabilities and strict quality control is crucial. This will maximize the stability of product supply and market competitiveness.
