Custom Injection Mold Components | Precision Mold Base & Mold Core Inserts for High-Volume Production

Engineering Precision Beyond Boundaries

Your Strategic Partner for Zero-Defect Injection Mold Tooling

At Senlan Precision, we don't just manufacture parts; we deliver the "Heart of the Mold." Our custom injection mold components and core inserts are engineered for Tier-1 automotive, medical, and high-end electronics industries where performance stability and micron-level accuracy define success.

By integrating world-class machining with strict ISO-certified quality control, we ensure your mold remains operational for millions of cycles with zero manual fitting required.

Solving the Precision Paradox in Injection Molding

1. Micron-Level Accuracy to Eliminate Flash

• The Issue: Inconsistent tolerances lead to poor mold shut-off, resulting in excessive flash and increased labor costs.

• Our Solution: Utilizing MAKINO High-Speed CNC and precision EDM, we maintain tolerances up to ±0.002mm. Our Mold Core Inserts ensure a perfect fit with the mold base, effectively eliminating flash even for high-pressure thin-wall molding.

2. Superior Metallurgy for Extended Mold Life

• The Issue: Tooling failure due to thermal stress, cracking, or surface wear.

• Our Solution: We utilize premium materials including 1.2344 (H13), S136 (STAVAX), and Beryllium Copper. Every component undergoes Vacuum Heat Treatment with triple tempering, reaching a balanced hardness of 48-54 HRC (or as specified) to maximize fracture toughness and wear resistance.

3. Total Interchangeability & Ready-to-Install Sets

• The Issue: High toolroom labor costs in the US and Europe due to parts requiring manual "Hand-Fitting."

• Our Solution: Our "Plug & Play" manufacturing philosophy ensures all Mold Base Components and Sliders are 100% compatible with DME, HASCO, and MISUMI standards. We guarantee that replacement parts will fit your existing mold base without any additional machining.

FAQ – Addressing Global Procurement Standards

Q: Can you manufacture matched sets of Core and Cavity inserts?

A: Yes. We specialize in matched manufacturing to ensure perfect shut-off and alignment, reducing mold tryout (T0) risks significantly.

Q: Do you offer specialized coatings for corrosive plastics like PVC?

A: Absolutely. We provide specialized PVD coatings such as TiN, CrN, or DLC to protect your inserts against chemical erosion and wear.

Q: How do you ensure the precision of complex sliders and lifters?

A: We use precision jig grinding and EDM to ensure that sliding surfaces have optimal clearance (typically 0.005mm - 0.01mm) for smooth operation without galling.
