Transparent plastic blow molding processing tips

In mold planning, attention should be paid to the following issues (including product planning) in order to avoid poor plastic molding caused by poor activity or uneven cooling, resulting in appearance defects and transformation. Generally, in mold planning, the following points should be noted:

The manufacturing process of transparent plastics

（1） The preparation and dryness of materials can affect the clarity of goods due to the presence of any impurities in plastic, thus affecting storage and transportation. During the feeding process, it is necessary to pay attention to sealing to ensure the cleanliness of the material. Especially when the material contains moisture, heating can cause the material to transform, so it must be dry, and it is necessary to use a dry hopper when adding materials during injection molding. It should also be noted that during the dry process, the input air should be filtered and dehumidified to ensure that it does not contaminate the material. The drying technology of Tongming Plastics: Data \ Technology Drying temperature (℃) Drying time (h) Material layer thickness (mm) Whitening PMMA70-802-430-40pc120-130>6<30 Choose hot air circulation drying PET140-1803-4 Choose continuous drying feeding equipment is preferred.

The blow molding process of transparent plastics

Due to its high light transmittance, Tongming plastic must have strict requirements for the appearance quality of plastic products, without any spots, pores, or whitening. Mist halo, black spots, discoloration, and poor gloss are the drawbacks that affect the quality of materials and equipment throughout the entire blow molding process.

The Processing and Forming Method of Plastic Rolling

1、 What is roll forming? Rotational molding, also known as rotational molding, rotary molding, rotary molding, etc., is a technical method for hollow forming of thermoplastic materials. Can be made into various shapes, sizes, and colors (both inside and outside) of plastic products. The product features integrated molding and can be manufactured with triple layers of foam as needed to enhance the strength of the barrel. The product is lightweight, tough, has strong impact resistance, and excellent drug resistance, making it a rare plastic processing and molding method.

What is blow molding and vacuum molding

1、 Blow molding: Blow molding is a method of processing plastic products by using compressed air to cause hollow plastic billets in a high elastic or plastic state to undergo expansion deformation, and then cooling and shaping them. According to the type of blow molded products, this processing method can be divided into hollow blow molding and thin film blow molding.
