Custom Prototype Silicone Molding Services
Plasticpartsmfg delivers technical custom silicone molding services for product developers, engineering teams, and OEMs. Operating from Shenzhen, we handle single-unit engineering validation through low-volume bridge production runs.
We fabricate functional, elastomeric parts with tight tolerances and complex surface textures directly from your 3D CAD models, master patterns, and engineering drawings.

Applications for Silicone Molding
Silicone is an essential engineering choice when thermal resistance, biocompatibility, and chemical inertness are mandatory. We fabricate components across consumer electronics, medical instruments, and industrial automation.
Seals & Gaskets
Custom-fit, liquid-tight sealing solutions engineered for IP67/IP68 enclosures and fluid delivery systems.
Soft-Touch Components
Tactile button membranes, handheld instrument sleeves, ergonomic handle grips, and protective bezels.
Flexible Housings
Impact-absorbing outer jackets and flexible protective boot designs for test equipment and ruggedized devices.
Functional Prototypes
Physical elastomer components for verification of assembly fit, elongation, drop impact, and ergonomic interaction.
Custom Dampening Pads & Mounts
Tailored durometer vibration isolators, internal shock bumpers, and laboratory-grade anti-slip feet configured for dampening mechanical resonance.
Why Choose Plasticpartsmfg for Silicone Parts?
We prioritize technical precision and process control to guarantee molded silicone parts fulfill strict engineering requirements.
Material Selection & Hardness
Silicone performance hinges on exact chemical balance. We help you choose the ideal grade across Shore A 10–80 to attain target elongation, tear resistance, and thermal tolerance.
Complex Geometry Reproduction
Our vacuum degassing and precision casting procedures capture deep undercuts, micro-textured surfaces, and thin membrane walls without causing micro-voids or sink marks.
Prototype to Production
From single verification parts to multi-cavity runs for field trials, our bridge-tooling workflow provides dimensional repeatability and short lead times from CAD release.
Project Workflow
A clear, sequential path from your engineering files to delivered silicone components.
File Review
Upload STEP, STL, or IGES CAD files accompanied by 2D critical dimensions.
DFM Analysis
Review parting lines, draft angles, wall thicknesses, and shrinkage compensation.
Tooling & Molding
Produce master patterns, prepare silicone tooling, and perform degassed casting.
Quality Inspection
Inspect key dimensions, Shore A durometer values, and surface finishes.
Delivery
Cleaned and packaged parts dispatched globally via express logistics.
