Key Benefits |
Applicable Mold Components |
|---|---|---|---|
|
1 |
Through Hardening + Low Temperature Tempering |
Comprehensively improves hardness, strength and wear resistance of the full part, ensures overall structural rigidity |
Cavity & core inserts, slides, lifters, punches, precision core pins |
|
2 |
Gas Nitriding / Plasma (Ion) Nitriding |
Forms a nitride hardened layer on the surface, greatly improves wear resistance, anti-galling and corrosion resistance with minimal distortion |
Ejector pins, sleeve ejectors, flat ejectors, core pins, guide bushes, slides, cavity/core molding surfaces |
|
3 |
Hard Chrome Plating |
Significantly improves surface hardness, wear resistance, rust prevention and surface finish; restores dimensions of worn parts |
Cavities, cores, guide pins, ejector pins, sleeve ejectors, slides, parts with dimensional deviation after wear |
|
4 |

Exceptional coating uniformity; reliable wear and corrosion resistance; no edge build-up effect |
Complex-shaped inserts, mold base plates, screws, springs, locating blocks |
|
5 |
Ni-P-PTFE Composite Coating |
Combines hardness of nickel layer with self-lubricating property of PTFE; extremely low friction coefficient and excellent demolding performance |
Lifters, slides, deep-cavity inserts, ejector pins prone to plastic sticking |
|
6 |
Titanium Nitride Coating (TiN) |
High hardness, excellent wear and adhesion resistance; reduces demolding resistance |

Cavities, inserts, ejector pins made of stainless steels such as S136, 420 |
|
11 |
Mold Polishing (Sandpaper + Oil Stone + Diamond Paste) |
Reduces surface roughness, improves finish, enhances demolding performance and product appearance |
Molding surfaces of cavities, cores, inserts and slides |
|
12 |
Mirror Polishing (Super Precision Polishing) |
Achieves optical-grade mirror effect for flawless product surface |
Molding surfaces of optical lenses, transparent housings, high-gloss acrylic molds |
|
13 |
Texturing / Etching (Chemical Etching / Laser Texturing) |
Creates surface textures such as leather grain, matte finish and brushed effect on product appearance |
Cavities, cores, molding surfaces of appearance parts |
|
14 |
TD Coating (Thermal Diffusion Carbide Coating) |
Forms vanadium/niobium carbide layer on the surface; ultra-high hardness, exceptional wear and galling resistance |
Deep drawing inserts, high-wear slides, long-life ejector pins and sleeve ejectors |
|
15 |
Hard Chrome + Mirror Polishing Composite |
Combines high hardness, high-gloss mirror finish and long-term rust protection |
Cavities of high-gloss transparent parts, mirror-finish mold cores |
