Custom Silicone Parts
Silicone, as a high-performance elastic material, comes in various
forms and can be processed and molded into high-precision and
complex parts using techniques such as injection molding,
calendaring, and extrusion. It can also undergo various surface
treatments, such as coloring, spraying, UV resistance, and
antibacterial treatments, according to specific requirements. Its
wide range of applications spans industries including medical,
food, automotive, electronics, and household products, meeting
diverse performance and aesthetic needs.
Silicone parts can be manufactured using various processing methods
depending on the application, complexity, and material properties
required. Here are the most common methods for manufacturing
silicone parts:
1. Compression Molding
How it works: A pre-measured amount of silicone material is placed
into a mold cavity. The mold is then closed and heated, compressing
the material into the desired shape.
Applications: Gaskets, seals, and O-rings.
Advantages: Cost-effective for small to medium production runs and
simple designs.
2. Injection Molding
How it works: Liquid silicone rubber (LSR) is injected into a
heated mold using a specialized machine, which cures the material
into a solid part.
Applications: Medical components, automotive parts, and electronics
like connectors or keypads.
Advantages: High precision, fast production, suitable for complex
designs, and ideal for large-scale production.
3. Extrusion
How it works: Silicone is forced through a die to produce
continuous shapes like tubes or profiles. The material is then
cured through heat or other methods.
Applications: Silicone tubing, cords, and seals.
Advantages: Best for continuous, long parts with uniform
cross-sections.
4. Liquid Injection Molding (LIM)
How it works: Similar to injection molding, LIM uses liquid
silicone injected into a mold, making it suitable for producing
parts with high consistency and precision.
Applications: Baby products, medical implants, and electronic
covers.
Advantages: High automation, precision, and repeatability.
5. Transfer Molding
How it works: Silicone material is placed into a chamber and then
forced into a mold cavity under pressure.
Applications: Complex parts with embedded components like metal
inserts.
Advantages: Suitable for intricate designs and medium-volume
production.
6. Casting
How it works: Liquid silicone is poured into a mold and allowed to
cure, either at room temperature or with heat.
Applications: Prototyping, molds, and large custom parts.
Advantages: Cost-effective for low volumes or custom designs.
7. 3D Printing
How it works: Silicone material is layered using additive
manufacturing techniques to create the desired part.
Applications: Prototypes and complex designs.
Advantages: Rapid production and design flexibility.
8. Die Cutting
How it works: Sheets of silicone are cut into specific shapes using
a die.
Applications: Flat silicone gaskets, seals, and pads.
Advantages: Ideal for thin, flat parts and high-volume production.
9. CNC Machining
How it works: Blocks or sheets of cured silicone are milled or cut
to create custom parts.
Applications: Prototypes, custom shapes, and large silicone parts.
Advantages: Suitable for low-volume production with high precision.
Choosing the Right Process
The choice of process depends on:
1. Part complexity: For intricate designs, injection molding or LIM is preferred.
2. Production volume: Compression molding is ideal for low to medium volumes, while
injection molding is better for large-scale production.
3. Material properties: Specific processes suit certain silicone formulations (e.g.,
liquid silicone for LIM, solid silicone for compression molding).
4. Application: For medical-grade parts, processes like injection molding and LIM
are more suitable due to their precision and cleanliness.
