Process sharing-TPU injection molding process

Hardness of TPU is usually expressed by internationally recognized Shore hardness. In general, A is expressed below 100 degrees, such as 80A, 90A, 95A, 98A, etc., and D is expressed above 100 degrees, such as: 50D, 60D, 64D, 71D, 74D, etc.There are many methods for TPU molding process: including injection molding, blow molding, compression molding, extrusion

What are injection molding process?

Injection molding process generally includes four stages of filling, holding, cooling, and demoulding. These four injection molding process stages directly determine molding quality of product, and the four injection molding process stages are a complete continuous process. 1. Filling stage of injection molding process (1) Filling is the first step in entire injection molding cycle, from the time

Impact of injection moulding process on product quality

Injection moulding process parameters mainly include baking temperature and time, injection amount, metering stroke (pre-plastic stroke), residual material amount, anti-delay amount, screw rotation speed, back pressure, injection speed and pressure, holding pressure and time, barrel temperature, mold temperature, cooling time, opening and closing speed and pressure, ejection speed, gas-assisted blowing pressure and time. Baking temperature and time

How to reduce bad smell and energy consumption during plastic injection moulding process?

Nowadays, moulding products can be seen everywhere in daily life or in the field of production and circulation. Moulding products refer to products which are plasticized and melted by injection moulding machine, injected into cavity of molding, cooled by cooling, melted and solidified, molded by injection moulding machine. These plastic products are inseparable from injection moulding. As a branch of
