Solid Silicone Compression Molding
Suitable for many gaskets, seals, pads, covers, boots and larger elastomer parts. Tool layout, charge placement, venting, curing and deflashing are planned around geometry and surface requirements.
Manufacturing Capabilities
Silicone molding selected around the part—not around a template
We evaluate geometry, material behavior, insert structure, volume and quality requirements before recommending compression molding, LSR injection molding or an overmolding route.
Core Processes
Manufacturing routes for industrial silicone projects
Liquid Silicone Rubber Injection Molding
Used for precision LSR components, thin or detailed features and higher-repeatability programs. Mold design must control filling, venting, flash, demolding and cold-runner behavior.
Silicone Overmolding
For plastic, metal, cable and electronic inserts that require sealing, cushioning, grip, insulation or environmental protection. Adhesion strategy and insert control are key inputs.
Insert Molding & Encapsulation
Components can be molded around stainless steel, metal, PC, PA and other project-approved substrates when the structure and material pair are suitable for the process.
Tooling & Prototype Samples
Tool construction, first trials and sample review are tied to a defined drawing revision. Findings from fill, flash, dimensional and assembly checks guide the next iteration.
Secondary Processing & Assembly
Project-dependent operations may include deflashing, post-curing, printing, surface treatment, part assembly, functional checking and customized packaging.
Overmolding Engineering
Bonding starts before material enters the mold
Overmolding success depends on the substrate, silicone formulation, surface condition, primer or self-bonding strategy, insert temperature, shutoff design and the loads seen in use.
- Substrate resin or metal grade confirmed
- Bonding area, undercuts and mechanical retention reviewed
- Insert location and movement during injection controlled
- Sealing interfaces separated from cosmetic surfaces
- Peel, pull or leak test defined when function requires it
Design for Molding
DFM questions we review before mold release
Flexible materials still need deliberate design. Early review helps avoid weak sections, unstable dimensions, trapped air, tearing during demolding and uncontrolled flash.
- Nominal wall and abrupt thickness transitions
- Draft, undercuts, parting line and demolding direction
- Gate, vent and allowable flash locations
- Hole, rib, membrane and sealing-bead geometry
- Reference dimensions and realistic silicone tolerances
- Assembly compression, stretch and mating-part condition
Process Selection
Inputs that affect mold route and quotation
Two parts that look similar can need different tooling when material, volume, flash, insert or validation requirements change.
Part Geometry
Size, wall, undercut, membrane, texture and demolding risk.
Material Need
Solid silicone or LSR, hardness, color and functional resistance.
Insert Structure
Plastic, metal, cable or electronics and the required bond interface.
Demand Profile
Prototype quantity, first order, annual usage and life-cycle expectation.
Quality Plan
Critical tolerances, appearance, tests, reporting and traceability.
