Blow molding material requirements and introduction

The development and application of blow molding technology is so extensive that it is complementary to the development of blow molding materials. Blow molding materials have gradually developed from the initial LDPE, PET, PP and PVC products, which can blow molding engineering plastics, rubber, and Some composite materials.

Special requirements for rubber materials in various blown plastics

A. Extrusion blow molding

Extrusion blow molding is carried out in a viscous flow state, so in order to reduce parison sag and optimize wall thickness distribution, plastics with larger molecular weights are usually used.

B. Injection blow molding

Injection blow molding is carried out under high elasticity. In order to reduce the energy consumption of injection molding parison, some easy-flowing plastics (plastics with smaller molecular weight) are used.

C. Injection stretch blow molding

Amorphous plastics are generally used because they are easier to stretch due to the smaller entanglement between molecules. Although PET also crystallizes, it is still the most important stretch blow molding material, and its crystallization speed is quite slow. In short, most blow molding grade plastics have a medium to high molecular weight distribution.

High Grade Blowing Molding Mould

 

In the blow molding process, blow molding mold is an essential and important part. A good blow molding mold makes the molding more smooth, the finished product more beautiful and smooth, and reduces the influence of burr on the appearance and use of the product.

 

About mould material:

 

* Steel S50C#: Basic material for blowing moulds, competitive price
* Steel P20#: Common blow molding mould material, medium quality
* 2316 stainless steel: High quality mould material stainless steel.
* S136H : High quality blow molding steel, very durable and strong.
* Aluminium 7075# inserted beryllium copper: the best blow molding mould material,

aluminium mould has good cooling, and beryllium copper is very durable as well.
