At JIESHENG HARDWARE, we specialize in manufacturing Die Casting Mold Precision Parts that meet the highest standards for performance, durability, and accuracy. With over 20 years of experience in precision CNC Machining, we provide custom die casting mold components designed to ensure the reliability and efficiency of your die casting operations.
Our team leverages advanced equipment and strict quality control to produce high-precision mold parts for automotive, electronics, lighting, household appliances, and industrial sectors.
What Are Die Casting Mold Precision Parts?
Die Casting Mold Precision Parts are the critical internal and external components of die casting molds that define the accuracy, surface finish, and lifespan of cast products. These parts are subjected to high temperatures, extreme pressures, and repeated stress during die casting operations. Therefore, they require tight dimensional tolerances, superior wear resistance, and optimal thermal management.
Common die casting mold precision parts include:
Mold cores & cavities
Mold inserts
Ejector sleeves & pins
Sliders & lifters
Core pins & cooling inserts
Sprue bushings
Die bases and support plates

|---|---|---|
| H13 / SKD61 / 1.2344 | Excellent toughness, thermal shock resistance, hardness after heat treatment 48-52 HRC | Mold inserts, cores, sleeves |
| S136 / 420SS | Corrosion resistance, excellent polishability, hardness 48-52 HRC | Cosmetic cavities, core pins |
| 8407 Supreme | Superior toughness, improved thermal fatigue | High-performance mold inserts |
| DC53 | High wear resistance, better toughness than D2 | Mold bases, lifters |
| BeCu (Beryllium Copper) | High thermal conductivity | Core pins, cooling inserts |
| Custom steels / tool steels per spec | — | As per customer request |
All materials are supplied with full material certificates, supporting RoHS, REACH compliance.
Surface Treatments for Die Casting Mold Precision Parts
We provide or coordinate professional surface treatments to enhance mold part durability:
Gas nitriding / ion nitriding – Surface hardening for wear and corrosion resistance
PVD coatings (TiN, TiCN, CrN) – Anti-galling, reduced friction
Hard chrome plating – Wear resistance, corrosion protection
Black oxide – Anti-corrosion for die bases
Mirror polishing / custom textures (VDI, EDM finish) – For cosmetic parts
Heat treatment – Quenching, tempering, stress relief (with full reports)
