Industrial Tooling Capabilities
Mold design depends on the material, part geometry, volume and manufacturing method. Explore key tooling options and the factors that influence cavity layout, venting and part quality.
Liquid Silicone Rubber (LSR) Injection Tooling
LSR mold manufacturing demands extreme precision and thermal management. LSR mold designs may use cold-runner configurations and controlled gating where the part geometry and equipment justify them. Runner strategy, venting, demolding and process compatibility should be reviewed together.
- Integrated cold runner systems with water-cooling channels
- Cavity count matched to part geometry and production volume
- Engineered with precise thermal barriers between cold decks and hot cavities
- Surface details and inserts reviewed against the part drawing
Compression & Transfer Molds
For processing high-consistency rubber (HCR) and industrial elastomers, we manufacture high-capacity compression and transfer molds. Transfer molds utilize integrated ITM pots and runner manifolds to distribute material evenly into closed cavities. Compression molds feature precision-ground land areas to ensure clean parting lines and simple deflashing.
- Precision-machined steel plates with optimized overflow channels
- Integrated transfer plunger and runner systems for balanced cavity filling
- Designed to resist severe clamping forces and hydraulic pressures
- Engineered for rapid demolding with manual or automated ejection plates
Tooling Materials & Engineering Specifications
We select premium tool steel and aluminum alloys based on your production volume, chemical corrosiveness, and cycle-time expectations.
Premium H13 Tool Steel
High-chromium hot-work steel providing outstanding resistance to thermal cracking and wear. Best suited for high-volume, abrasive compounds and medical LSR injection tooling.
Pre-Hardened P20 Steel
A versatile alloy providing excellent dimensional stability and uniform hardness. Highly cost-effective for medium-to-large compression molds and complex industrial plates.
High-Conductivity Aluminum
Specialized aluminum alloys featuring superior heat transfer and lightweight handling. Ideal for rapid prototyping, low-pressure molding systems, and accelerated cycle trials.
Advanced Surface Treatments
Available with Chrome plating, Teflon coatings, and chemical vapor deposition (CVD) to lower demolding friction, prevent residue build-up, and extend tool lifespans.
CAD/CAM Tooling Engineering & Simulation
A tooling review starts from your 2D drawing or 3D CAD file (such as STEP, IGES or DXF), along with material and production requirements. We optimize the cavity layouts, position parting lines to minimize flash, and locate venting channels to prevent burn marks or voids.
Critical dimensions, shrinkage allowances and sample inspection criteria are reviewed for the intended compound and process. Applicable tolerances and verification methods should be agreed for each project.
