Core Engineering Capabilities
We design and build production-ready injection molds tailored to your specific mechanical, cosmetic, and volume requirements. Every tool is engineered using advanced CAD/CAM systems (UG/NX, SolidWorks) and validated via CAE mold flow simulation prior to cutting steel.
Mold Design & Simulation Parameters
• Typical Tolerance Capability: +/-0.01mm to +/-0.02mm (adjusted for part geometry and resin shrinkage).
• DFM & Mold Flow Analysis: Evaluates gate location, weld line distribution, volumetric shrinkage, and cooling efficiency to eliminate short shots, warpage, and sink marks before machining.
• Complex Mechanisms: Expert in multi-cavity layouts, hydraulic/mechanical slide actions, lifters, collapsible cores, and hot-runner systems (Yudo, Synventive, etc.).
Steel Selection & Tool Lifespan
Tool steel is selected based on your target production volume, abrasive properties of the resin, and surface finish requirements.

Frequently Asked Questions
Q: What inputs are required to start a mold design?
A: Please provide 3D product files (STEP, IGES, or STL format), target plastic resin grade, desired surface finish (SPI or VDI standard), and estimated annual production volume.
Q: Do you perform trial testing before shipping the mold?
A: Yes. Every mold undergoes T1 trial sampling using your specified resin. We inspect part dimensions and surface cosmetics, and supply initial trial samples along with a complete inspection report and processing parameter log.
Q: What is your policy on mold ownership and maintenance?
A: The mold belongs entirely to the client upon final payment. We maintain detailed tool history records and supply replacement wear components (e.g., ejector pins, springs) upon request.
