Customized processing process:

1. Mold customization and manufacturing.   

Custom mold: According to the 3D drawings provided by the customer, understand the size, shape, and finish of the product.   Material selection: Commonly used mold materials include steel, aluminum, and resin.   CNC machining or 3D printing: Manufacturing molds through CNC machining or 3D printing technology.

2.PREPARATION OF SILICONE RAW MATERIALS:

Silicone Type Selection:

Choose between liquid silicone rubber (LSR) and high-temperature vulcanizing silicone (HTV) based on specific application requirements. Color Allocation: Incorporate color paste or color masterbatch to achieve the desired hue. Additives: Introduce functional additives, including antistatic agents, flame retardants, and high-temperature resistant agents, as necessary.

3.Molding process

Molding:

The silicone material is put into the mold and formed by heating and pressure.

Suitable for complex shapes and high precision products.

Injection molding:

Liquid silica gel (LSR) is injected into the mold by an injection machine.

Suitable for mass production and high precision products.

Extrusion Molding:

Using an extruder to shape silicone into continuous forms such as strips or tubes.

Ideal for products like silicone tubes and sealing strips.

Calendering Molding：

Silicone is calendered into sheets or films, which are suitable for applications such as silicone gaskets and protective films

Post-Processing Techniques

Trimming: Removing flash and excess material after molding.

Surface Treatment:

Spray Coating: Enhancing surface gloss or adding special functionalities (e.g., anti-slip, anti-fouling).

Printing: Applying text, patterns, or logos onto the silicone surface.

Laser Engraving: Used for intricate patterns or text.

Secondary Vulcanization: Improving the physical properties and stability of the silicone.

Bonding: Adhering silicone components to other materials (e.g., metal, plastic).

Quality inspection

Dimensional inspection: To ensure that the product meets the design specifications.

Performance test: including tensile strength, wear resistance, temperature resistance, etc.

Appearance inspection: Check the surface for defects, such as bubbles, impurities, etc.

Special technology

Embedding molding: metal, plastic and other components are embedded in silicone to form an integrated product.

Two-color molding: Through multiple injection molding or molding, the manufacture of two-color or multi-color silicone products.

Foaming process: Manufacture lightweight, soft silicone foam material.

Packaging and delivery

Cleanliness: To ensure that the product is dust-free and pollution-free.

Packing: dustproof and moisture-proof packing according to customer requirements.

Transportation: Arrange logistics to ensure safe delivery of products
