Detailed introduction:
The temperature control of the storage chamber is also a question, as some polymers may degrade during the processing, especially when the processing temperature is high or the melt needs to stay in the storage chamber for a period of time during intermittent blow molding. In addition, blow molding grade polymers contain various additives, which can form by-products during the melting process. These degradation products or by-products will accumulate in the flow channel of the machine head, causing stripes on the surface of the billet and affecting the appearance and function of the product. So adhering to the cleanliness of the machine head is an important condition for blow molding high-performance products
