The template of the extruder consists of a template body with a discharge hole and a heat insulation layer, and is fixed to the die head with a threaded rod. Only when the discharge speed of each die hole is consistent can particles of uniform size be cut out. During use, there are many factors that affect the smooth flow of the template. When the template is severely blocked, it will affect the appearance of the particles, the service life of the cutter, and cause shutdown.

With the rapid development of the economy, human awareness of environmental protection and product requirements have been continuously improved. TPE (Thermoplastic Elastomer) is a material with high elasticity, high strength, high resilience of rubber, and can be injection molded. It is non-toxic and environmentally friendly, has excellent colorability, weather resistance and temperature resistance, and has excellent processing performance. It can be recycled and coated and bonded with base materials such as PP, PC, PS, ABS, etc., or it can be molded alone. TPE has both the processing performance of thermoplastics and the physical properties of vulcanized rubber. It is an advantageous combination of the advantages of plastics and rubber. Providing customers with a TPE material formula with low price, high yield rate, and excellent performance has always been the core pursuit of TPE granulation manufacturers.

The amount of color masterbatch added to the final resin is generally 2%-5%. If the color masterbatch is mixed and added correctly, the content of the carrier resin in the final mixture will account for 1%-3% or more. This makes it the most abundant additive in the additive family, so some details should be paid attention to when selecting the carrier resin. For example, users' requirements for color, color stability, environmental requirements, and the role of masterbatch in the final product, etc., make the formulation of masterbatch increasingly complex.

White masterbatch seems strange to many people but is so familiar. Almost everyone has used it. It has bright and eye-catching color, high tinting strength, good dispersion, high concentration, good whiteness and strong hiding power. , with the characteristics of good migration resistance and heat resistance, it is widely used in injection molding, blow molding, wire drawing, casting, extrusion, film blowing, foaming, sheet, pipe, pelletizing, hollow, EVA, bottle blowing, Sheet materials, household appliances, toys, packaging materials, wires and cables, plastic bags, automobiles, building materials, sports and leisure products, packaging bags, packaging bottles and other plastic product industries.

The specific structure of plastic twin-screw extruders is based on the actual twin-screw extruders, and specially designed twin-screw extruders can be divided into meshing types and non-meshing types according to the relative positions of the two screws. Plastic twin-screw extruders can arrange and combine thread elements and barrel elements of various geometric shapes. Based on experience-theory-practice-test, the design can be optimized for different mixing requirements to adapt to the needs of different process formulas, making the co-rotating twin-screw extruder highly adaptable.

As an environmentally friendly mechanical production equipment, plastic pelletizers produce useful granular plastics, but for these plastic production machinery and equipment, necessary maintenance is still required, especially in daily life. Some maintenance before and after production can maintain the normal operation of the equipment and extend its service life, which is also very good for users.

The six basic characteristics of flame retardant PP:1. Mechanical properties 2. Physical performance 3. Chemical stability 4. Thermal performance 5. Weathering resistance 6. Electrical performance

When we really want the additive to be evenly distributed throughout the polymer matrix, we would claim that we need to improve dispersion. Or we design the screw to have a distribution mixing element, but the material is easy to agglomerate and needs to be dispersed first before being distributed.

Plastic modification is a method of improving the quality of plastics by adding additives, fillers, etc. to alter their properties. Meanwhile, plastic modification is also the most effective way to reduce the cost of plastics. The elements of formula design in plastic modification mainly include material selection, compounding, dosage, and mixing method. The interaction between various elements can be either mutual assistance or mutual cancellation. Therefore, designing a high-performance, easy to process, and low-cost formula is not an easy task.

Nylon (PA) has a series of excellent properties such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubricating, and easy processing and molding, and has become one of the widely used thermoplastic engineering plastics both domestically and internationally.
