Product Description

Premium Injection Molding Machine Head Plate – Durable, High-Precision, and Universal Compatibility

Upgrade your injection molding process with our high-strength head plate, engineered for exceptional stability and long-lasting performance. Made from hardened alloy steel (P20/718/H13)and precision-machined to ±0.02mm flatness, this head plate ensures accurate mold alignment and reduced wear for consistent production quality.

Universal Compatibility – Fits most horizontal/vertical injection molding machines.
 

Superior Surface Treatment – Chrome-plated or nitrided for corrosion resistance and extended service life.
 

Customizable Options – Available in standard sizes or tailored to your CAD drawings.
 

Industry-Proven – Ideal for automotive, electronics, and medical mold applications.

Material

Head Plate Material Requirements: High strength, rigidity, wear/fatigue resistance. Common options :

1. Carbon Steel (Mainstream Choice)
(1)Q235B/S355JR: Cost-effective and widely used for low-to-medium load machines. Requires heat treatment (quenching and tempering) to enhance strength.
(2)45# Steel: After tempering, hardness reaches HRC 25-35, offering balanced performance at moderate cost.

2. Alloy Structural Steel (High-Performance Machines)

42CrMo/40Cr: Quenched and tempered for tensile strength exceeding 1000MPa, with excellent fatigue and impact resistance. Ideal for large-tonnage machines (e.g., 2000T+).

3. Cast Iron (Special Applications)
HT250/HT300: Good damping and vibration absorption, but lower tensile strength. Often used in small or older machines.
Ductile Iron (QT500-7): Strength close to steel, suitable as a carbon steel alternative.

4. Special Treatments

Surface Hardening/Nitriding: Increases wear resistance (e.g., hardness ≥HRC 50) for guide rail contact surfaces.
Stress Relief: Large head plates require vibration aging or annealing to prevent post-machining deformation.

Application

1.Mold Clamping Function

The head plate works with the tail plate to firmly clamp the mold via the locking mechanism, preventing mold displacement during injection.High parallelism and flatness are critical to avoid flash or dimensional defects.

2.Dynamic Load Resistance

Withstands high-pressure injection and clamping forces (typically tens to thousands of tons), resisting elastic deformation to ensure mold sealing.Fatigue resistance is essential for long-term cyclic stress.

3.Guidance & Alignment

Coordinates with tie-rods (guide pillars) to ensure smooth movement of the moving plate and maintain mold concentricity.

4.Multi-Process Compatibility

Adapts to diverse materials:

(1)Standard/engineering plastics (e.g., nylon, PC)
(2)Metal Injection Molding (MIM)
