How to manufacture good silicone swim cap

How to manufacture good silicone swim cap

Manufacturing a swim cap is a process that involves several steps, mainly including material preparation, mold making, molding, and vulcanization treatment. The following are the basic steps for manufacturing swim cap:

1. Material preparation:
- According to the requirements of the swim cap, prepare suitable silicone materials. Silicone materials are generally divided into liquid silicone and solid silicone, liquid silicone is suitable for injection molding, solid silicone is suitable for hot pressing molding.

2. Mold making:
- Making molds for silicone swim cap. Moulds are usually divided into metal moulds and silicone moulds, metal moulds are suitable for mass production, silicone moulds are suitable for small batch production or personalized customization.

3. Injection molding:
- The prepared liquid silicone is injected into the mold, and then processed by high temperature and high pressure to make the silicone material solidify and cure quickly to get the preliminary molded silicone swim cap.

4. Surface treatment:
- Carry out surface treatment for the silicone swim cap, including coating, printing, embossing and other processes, in order to increase the smoothness, waterproof performance and aesthetics of the swim cap.

5. Quality Inspection:
- Appearance inspection of the produced silicone swim cap to ensure that the product has no flaws and defects, as well as tensile strength test and other quality tests.

6. Vulcanization treatment:
- After the cap is demolded and lined with cardboard, it is placed flat on the vulcanizing car and entered into the vulcanizing tank for vulcanization, the vulcanizing temperature is usually 135℃ and the vulcanizing time is 20 minutes.

7. Stick rubber strip:
- The vulcanized products will be cooled to below 50 ℃ when demolded for inspection, and the products after passing the inspection will be turned over and set on the ceramic mold for sticking the adhesive strip.

The above steps provide a basic process for manufacturing swim caps, the specific material ratio and process parameters may vary according to specific product requirements and production conditions. When manufacturing the swim cap, it is also necessary to consider the comfort and practicality of the swim cap, such as providing a detachable portion that is easy to remove to improve the comfort of the user, or providing a reflective layer on the outer peripheral side of the body of the swim cap to improve safety. In addition, the choice of material for the swim cap is also very important. Silicone swim caps are favored because of their good elasticity, high tightness with the head, suitable for keeping warm in winter and not easy to fall off.

What are the key points for the mold design of swim cap

The following points need to be considered when designing the mold for swim cap:

1. Accuracy and quality: Mold making requires steps such as design, engraving, processing and assembly to ensure the accuracy and quality of the mold.

2. Positioning accuracy: the blank placed on the mold should be accurately positioned, should try to use the holes in the parts to locate, or design the process holes in the blank.

3. Prevent the blank from sliding or shifting: in the process of bending, the blank should be prevented from sliding or shifting, for the very large size of the parts, the blank compression device as far as possible to use the air cushion on the press.

4. Structural design: the structural design of the swim cap mold needs to take into account the shape and function of the swim cap, such as the waterproof silicone swim cap has a ring-shaped airbag on the inside of the swim cap against the lower edge of the mouth to achieve a better waterproof effect.

5. Material selection: the material used for the swim cap, such as 100% silicone material, is chosen because of its good waterproof effect.

6. Design for easy removal: Considering the convenience of removing the swim cap, the design should include a cap removing part that is easy to remove the body of the swim cap, such as the fixing blocks set on the two opposite sides of the body of the swim cap, and a number of finger holes vertically opened on the two fixing blocks for the fingers to pass through.

7. Reinforcement structure: In order to improve the strength and durability of the swim cap, it may be necessary to include reinforcing bars or reinforcing ligaments in the design of the molds, so as to reduce deformation and improve the fit.

8. Comfort and Practicality: The design should also take into account the comfort and practicality of the swim cap, such as setting up a number of convex strips to increase the strength of the swim cap, and at the same time reduce the direct contact between the swim cap and the skin on the head, so as to improve the comfort of wearing the swim cap.

9. Safety: Considering the visibility of the swim cap in a dark environment, the design may need to provide a reflective layer on the peripheral side of the swim cap body to improve safety.

10. Anti-skid design: To ensure that the swim cap will not fall off from the head while swimming, the mold design may need to provide anti-skid pattern on the inner side wall of the brim to increase the friction.

These points cover the key aspects of swim cap mold design, from structure and material to functionality and safety, all of which need to be taken into account during the design process.
