Parameters/spectroscopy introduction

Bimetal barrel is a layer of 2-3mm wear-resistant and corrosion-resistant on the inner wall of the barrel.

High temperature resistant alloy

Its effective service life is greatly improved than that of ordinary nitriding barrels

For processing engineering plastics, fluoroplasty, polysulfone, PPO special types of plastics, etc.

Bimetallic superiority is particularly obvious

Our company can use screws for different functions

We use different alloys and welding methods.

Screw:

1. Ordinary nitride screw (SACM645)

2. Top spray welding double alloy

3. Full coverage tungsten steel screw

4. Full hard series NPT1, NPT2, NOT3

5. Ceramic film and diamond film are generated on the surface

Barrel:

1. Ordinary Nitriding (SACM645)

2. Centrifugal cast alloy in inner hole (particularly divided into ABC third grade and)

3. Full hard inner sleeve series (NPT1, NPT2NPT3

Product Advantages:

The special alloy layer on the surface of the dual alloy screw can effectively resist the erosion of various corrosive media, and at the same time has good wear resistance, so that the screw still maintains excellent performance in a long-term and high-strength working environment, greatly extending its service life. The special alloy material allows the dual alloy screw to maintain stable physical and chemical properties under high temperature environments, ensuring the smooth progress of the extrusion process, and is especially suitable for processing high-temperature melting engineering plastics. The precision-treated alloy surface not only has high hardness but also has good finish, reducing friction and resistance during the extrusion process, improving production efficiency and product quality. It solves the problem that traditional chrome-plated screws are prone to fall off the chrome-plated layer, avoids environmental pollution and product quality problems caused by the fall off of chrome-plated layer, and meets the environmental protection requirements of modern manufacturing. At the same time, the dual alloy screw has strong chemical stability and is not easy to react with injection molding materials, ensuring the stability and reliability of the product. The extrusion machinery using dual alloy screws can reduce energy consumption while maintaining efficient production, and improve overall production efficiency and economic benefits.
