Compression Moulding Finishing Options
Compression molding is a highly efficient manufacturing process widely used to produce high-quality, durable components from a variety of materials, including silicone, rubber, and plastics. This process involves placing a pre-measured amount of material into a heated mold cavity.
Trimming and Deflashing
Remove excess material, known as flash, that may have seeped out of the mould during the compression process.
Surface Texturing
Modify the surface finish of the moulded part to achieve specific tactile or visual properties.
Bonding and Assembly
Join multiple moulded components together or attach additional elements to the moulded part.
Machining and Drilling
Add holes, slots, or other features that cannot be achieved during the initial moulding process.
Polishing
Achieve a smooth, glossy finish on the moulded part, often required for aesthetic purposes or to meet strict surface finish specifications.
Printing and Marking
Apply logos, part numbers, or other markings to the finished product for identification, branding, or instructional purposes.

Advantages of Silicone Compression Molding
Silicone Compression Molding offers several advantages, making it an attractive option for many applications. It’s well-suited for both low and high-volume production runs and can efficiently handle a wide range of product sizes and complexities. The process permits the use of high-viscosity, high-strength silicone rubber, allowing the creation of products with exceptional durability and resilience.
- Minimal lead time: Short set up a time
- Easy to prototype: Minimal wastage
- Widest range of part sizes: Perfect for the manufacturing of parts with a very large cross-section
- Dimensional stability: Capacity to process stiff, high durometer materials, Excellent for low quantities of parts requiring a long cure time
- Low tooling and equipment costs: Tooling is simpler and more cost-effective than injection molding, Although this technique has a longer cycle time, it is a low-pressure mold, which means it’s inexpensive to produce a variety of cavities without high tooling costs.

Compression Moulding Fundamentals
How does compression moulding work?
- Raw materials include resins in the form of pellets, powder, or preforms. This charge material is usually plastic or composite, and is often preheated and placed into a heated mould cavity.
- The matching half mould or top plug is closed using a hydraulic press.
- This motion creates vertical compression and during this time, the pressure forces the plasticized charge to fill the mould evenly, creating a uniform part structure.
- The mould is kept closed and the high temperature cures the charge material into the final shape and chemistry.
- Once the curing reaction is complete, the upper mould is lifted, and the final product is removed.
Why would you choose compression moulding over injection moulding?
Compression moulding wastes less material than injection moulding, as no runners, sprue, or gates are required to form the part. Consequently, this technique produces an aesthetically as well as a functionally superior surface finish. This makes it the go-to technique for large flat and curved components and for low-production volume.
This technique outperforms others when composite materials are used to give extra stiffness, corrosive resistance, durability, and other special material properties.
