Nitrided Orvar Supreme Precision Mold Parts

Gear Components & Thread Core Inserts for Injection Molds

Product Overview

Our Nitrided Orvar Supreme precision mold parts, including gear components and thread core inserts, are engineered for high-performance plastic injection molds operating under high pressure and high cycle conditions.

Manufactured from Orvar Supreme premium hot work tool steel, these components are vacuum heat treated and surface nitrided to achieve an optimal balance of toughness, wear resistance, and dimensional stability.

They are widely used in:

• Plastic gear molds

• Cosmetic cap thread molds

• Multi-cavity packaging molds

• Automotive plastic component molds

• Medical and high-precision injection tooling

All components are produced strictly according to customer drawings (Built-to-Print / OEM manufacturing).

Material – Orvar Supreme (Premium H13 Grade)

Orvar Supreme is an advanced ESR-remelted hot work tool steel known for:

• Excellent toughness

• High thermal fatigue resistance

• Good dimensional stability

• Superior polishability

• Stable performance in high-cycle molds

Compared with standard H13 grades, Orvar Supreme provides:

• More uniform microstructure

• Better crack resistance

• Longer mold service life

Surface Treatment – Controlled Nitriding

Surface treatment plays a critical role in thread and gear components.

Our nitriding process provides:

• Increased surface hardness

• Improved wear resistance

• Reduced friction during demolding

• Enhanced resistance to plastic material abrasion

Nitriding improves surface durability while maintaining core toughness.

Typical Applications

These precision mold components are suitable for:

Plastic Thread Cores

• Cosmetic bottle caps

• Pump closures

• Medical screw-type packaging

• Rotational consumer product components

Plastic Gear Inserts

• Small transmission gears

• Electronic gear components

• Functional rotating assemblies

• Automotive interior mechanism parts

They are especially suitable for multi-cavity molds where consistency across cavities is critical.

Engineering Focus & Machining Control

Thread cores and gear inserts require extremely precise machining to ensure:

• Correct tooth geometry

• Accurate thread pitch

• Stable torque transmission

• Smooth demolding

• Reduced wear and sticking

1) Dimensional Precision

• Tolerance capability: up to ±0.002 mm

• Concentricity and axiality strictly controlled

• Stable repeatability across batches

2) Gear & Thread Profile Accuracy

• CNC machining + EDM profile forming

• Controlled flank angle and pitch accuracy

• Uniform engagement performance

3) Surface Finish

• Fine polishing available

• Low surface roughness for smooth mold release

• Reduced friction and wear
