Product introduction

Zhoushan double alloy screw barrel screw type: [different plastic properties, you can choose a screw with a different structure, which can improve the plasticizing effect] gradual type, sudden type, wave type, barrier type, double screen type, shunt type, separation type , Exhaust type, pin type, mixed type, double head type, three head type, multi head type, etc.

Detailed introduction

舟山 Double alloy screw barrel

Introduction:

The double-alloy extruder barrel screw can be widely used in central air-conditioning, domestic air-conditioning and various types of hot and cold pipes, containers, and heat insulation in the construction, chemical, metallurgical, shipbuilding, pharmaceutical, and vehicle industries. Thermal insulation products.

Type and use:

Ordinary type, progressive type, sudden change type, kneading type, separation type, pin type, exhaust type, barrier type, split type, wave type, acceleration type and above screw types are suitable for spinning, granulating, drawing, blown film, Extruded header, foamed, extruded sheet, extruded board, etc.

Features:

1.Abrasion resistance and long life;

2. High temperature resistance, no deformation under high temperature;

3. Corrosion resistance, the material is corrosive;

4. Good cutting performance;

5, high strength, can withstand large torque, high speed;

6. Small residual stress and small thermal deformation after heat treatment.

Routine maintenance:

1. Do not start the machine when the screw does not reach the preset temperature.

2, to prevent metal fragments and debris from falling into the hopper, if processing recycled materials, you need to add a magnetic hopper to prevent iron filings from entering the barrel.

3. When using anti-salin, make sure that the plastic in the barrel is completely melted, so as not to damage the transmission system parts when the screw is retracted.

4. When using new plastic, the remaining material of the screw should be cleaned.

5.When the temperature of the molten plastic is normal, but the black spots or discoloration of the molten plastic are continuously found, the rubber screw should be checked.

6. During processing, try to plasticize the material as much as possible, do not allow metal foreign matter to be mixed into the material, and reduce the screw torque.

Explanation:

The material of the product is made of high-quality gold-containing steel (38CrmoALA), which is precision-made by adjustable quality and qualitative, surface nitriding, polishing and other processes.

We can not only make samples and manufacture, but also design, survey and manufacture according to the special requirements of customers, or use bimetal repair work for old screws. The service life of bimetal screws is 3-5 times longer than that of ordinary nitride screws .
