Engineering Molds
Built to Scale
Precision mold design is the foundation of consistent silicone manufacturing. With 15 years of OEM/ODM expertise, we engineer tooling that balances aesthetics, efficiency, and longevity--turning concepts into production-ready assets.
Product Structure &
Molding Process Analysis
Every mold begins with a thorough analysis of product geometry, wall thickness, and functional requirements. We evaluate whether solid silicone compression molding or liquid silicone injection (LSR) best suits your product's performance targets and production volume.
Material Compatibility
Selecting between HTV solid silicone and LSR liquid silicone based on hardness, transparency, and food-grade requirements.
Geometric Feasibility
Reviewing undercuts, radii, and wall uniformity to prevent demolding issues and ensure mass production reliability.
Production Volume Match
Aligning tooling steel grade and cavity count with projected monthly output to optimize unit cost.
Parting, Gating, Venting
& Ejection Engineering
The four pillars of successful silicone tooling. Our engineers meticulously design each element to minimize flash, eliminate air traps, and ensure clean product release.
Parting Line
Strategic placement along natural product edges to hide seams and maintain aesthetic integrity.
Gating System
Pin-point, submarine, or edge gates calibrated for optimal flow and minimum material waste.
Venting Design
Micro-venting channels prevent trapped air, burn marks, and incomplete filling in deep cavities.
Ejection Method
Air-blow, stripper plate, or manual ejection selected to protect delicate silicone surfaces.
Shrinkage, Tolerance
& Cavity Layout
Silicone's unique shrinkage behavior demands precise mathematical compensation. Our team calculates shrinkage rates per material grade, applies tolerance stacks, and optimizes cavity layouts for balanced filling.
-
Material-Specific Compensation
Shrinkage data applied per silicone grade (HTV, LSR, FKM) and durometer.
-
Balanced Runner Systems
Symmetrical layouts ensure every cavity fills uniformly, reducing scrap rates.
-
Multi-Cavity Scaling
From single-cavity prototypes to 64-cavity high-volume tooling solutions.
Balancing Aesthetics,
Efficiency & Lifespan
Great mold design is a trade-off science. We engineer the optimal equilibrium between beautiful surface finish, fast cycle times, and extended tool life.
Aesthetic Finish
Mirror polish, matte texture, EDM finish, or custom patterns tailored to your brand identity.
Cycle Efficiency
Optimized cooling channels and ejection timing reduce cycle times by up to 30% versus industry standard.
Mold Longevity
Hardened P20, 718H, or S136 steel treatments extend mold life beyond 500,000 shots.
Design Review &
Documentation
Before any steel is cut, every mold design undergoes a comprehensive DFM review with the client. Full documentation ensures transparency and alignment at every stage.
DFM Report Delivery
Detailed design-for-manufacturing analysis highlighting potential risks, draft angle issues, and material flow concerns.
3D Mold Flow Analysis
Simulation of silicone flow, cooling, and shrinkage to predict and prevent defects before tooling begins.
Client Design Review
Collaborative session to walk through parting lines, gate locations, and surface finish specifications.
Written Sign-Off
Formal approval documents including 2D drawings, 3D files, BOM, and tooling specifications archived for traceability.
