This technique is characterized by a complex die design with separate melt paths merging close to the exit. Different layers are formed by varying the flow rate and thickness of each. It is suitable for polymers with varying viscosities and melt temperatures. However, the cost of capital equipment and maintenance is high.
The material is environmentally friendly because it can be recycled. It has outstanding properties including acid and alkali resistance, electrical insulation and low temperature toughness. The HDPE COEXTRUSION MOULD features an optimized flowing channel, high stability, and fast extrusion speed. Hubei tianrui plastic mould co., LTD is a professional manufacturer with more than three thousand square meters of workshop space and 60 experienced staff. Its expert designers and experienced workers have over 21 years of experience in the industry.
PET
The PCR, or polymer chain reaction, can affect the appearance of the finished container. To compensate for this, some PET recyclers add toner to the moulding process. Others deliver coloured pellets to their customers. Other technologies help to extend the shelf life of products by preventing them from absorbing oxygen, moisture, or light. However, these technologies can also negatively affect the taste and freshness of products. Barrier technologies can be present on the inner layers of food grade containers. These containers can also incorporate multilayer technologies.
HDPE, or high-density polyethylene, is a petroleum-based thermoplastic. It is remarkably durable and is resistant to impacts, punctures, and corrosion. It is a sustainable plastic, too, and is often used in packaging for perishable items and hazardous goods. A high-density polymer, like PET, can be processed into a variety of products, from packaging materials to clothing fibers and beverage containers.
TPE
The HDPE EXTRUSION MOULD is a process whereby a plastic material is melted into a mouldable state, then transferred into a cavity of the mold in "A" and "B" parts. The material then begins to harden and cool to the exact shape of the mold cavity. When it is completely set, the parts eject from the mold. This process can be repeated many times and is customized to meet your project's requirements.
The disadvantages of coextrusion are high tooling costs, a relatively small part range, and a need for solid handle-ware. While both extrusion processes have advantages, coextrusion is usually more economical for small products. However, once the market for these products grows, large complex shapes can be fabricated. Similarly, coextrusion and biaxial orienting EBM have similar advantages. However, the advantages of coextrusion outweigh their disadvantages.
PPO
A PPO HDPE extrusion mould can be utilized to manufacture composite material with improved flow characteristics. The extrusion mould has a vacuum forming process for preparing the HDPE and PPE plate. The present invention utilizes a combination of technical solutions and low-cost plastics sucking moulding processes to manufacture a PPO HDPE extrusion mould. The following are some of the advantages of this extrusion mould.
PP: The world's second most popular plastic is used in extrusion molding. Similar to HDPE, PP has lower density and stiffer characteristics. Its lower density and molder-friendliness make it an excellent choice for high-temperature applications. PP is translucent and colorable. It has a low coefficient of thermal expansion. This material is also widely used in automotive fuel tanks.
