Plastic extrusion mold

Extrusion mold is the core part of extrusion production ,the technical state of extrusion mold is directly related to the stability of extrusion production ,the quality of extrusion products ,extrusion production efficiency and the service life of the mold itself.

In processing ,usually powder or granular form of polymer added to the extruder cylinder ,under the action of the screw or plunger ,the polymer along the groove or cylinder forward ,and gradually melt and become sticky fluid ,and then through the mold set at the end of the cylinder , the formation of the shape of the mold ,finally by cooling ,can be formed for the required shape of products ,such as all kinds of plastic pipe ,sheet ,plastic steel doors and window,film,decorative with kicking ,etc.

Therefore ,the design of the extruded mold is very important.

Product Overview

Our Plastic Extrusion Dies are engineered for high-performance polymer shaping, delivering ultra-precise profiles for tubes, sheets, films, and complex geometries. Designed for compatibility with single/twin-screw extruders, these dies ensure consistent output, minimal material waste, and extended service life across industries like packaging, automotive, construction, and consumer goods.

Key Features

1. Advanced Design & Materials

Die Body Construction:

Material: Premium tool steel (H13, D2) or carbide-coated alloys for wear resistance.
Surface Treatment: Nitriding, chrome plating, or mirror polishing (Ra ≤0.3μm) to reduce friction and adhesion.
Thermal Stability: Withstands continuous temps up to 400°C and pressures up to 100MPa.

Flow Channel Optimization:

CAD/CFD Simulation: Ensures uniform melt flow distribution (≤5% deviation).
Adjustable Lip System: For real-time thickness control (±0.05mm tolerance).
Modular Design: Quick-swappable inserts for multi-profile production.

2. Versatile Die Types

Flat Sheet/Film Dies: Cloeren-style or coat-hanger designs for PP, PET, PVC.
Pipe/Tubing Dies: Spiral mandrel or crosshead dies (up to 2000mm diameter).
Profile Dies: Custom shapes for window seals, automotive trims, and technical profiles.
Co-Extrusion Dies: Multi-layer compatibility (2-7 layers) for barrier films.

3. Precision Engineering

Tolerance: ±0.01mm for critical dimensions (ISO 2768-mK standard).
Cooling Channels: Integrated water/oil circuits for rapid thermal management.
Ease of Maintenance: Split-body design for fast cleaning and polishing.
