The helmet industry still has a very large market potential.Helmets play a protective role during travel, so they are an essential protective measure for anyone who enjoys outdoor sports and cycling.Helmets are beloved both in China and abroad. The Ministry of Public Security's slogan of "One helmet, one belt" in 2020 has inspired many office workers to use helmets. What are the materials and manu...

1. Preface Carbon fiber refers to the high strength and high modulus fiber with carbon content above 90%. The high temperature resistance is the first among all chemical fibers. It is made of acrylic and viscose fiber as raw material and oxidized and carbonized by high temperature. Material characteristics: carbon fiber is mainly composed of carbon elements, with high temperature resistance, anti-...

Long fiber reinforced thermoplastics (LFRT) are being used for injection molding applications with high mechanical properties. While LFRT technology can provide good strength, stiffness and impact properties, the processing method of this material plays an important role in determining what properties can be achieved in the final part. In order to successfully mold LFRTs, an understanding of some ...

Long fibre reinforced thermoplastics (LFT) is the most commonly used base resin for LFT, followed by PP, PA and also PBT, PPS, PPA, TPU and other resins. It is worth mentioning that different fibers are needed for different resins to achieve better results. Development of LFT In 1980, Polymer Composites Corporation (PCI), USA, was the first to propose the theoretical design concept of LFT, and con...

Polyamide resin, the English name for polyamide, PA for short, commonly known as nylon (Nylon). It is a macromolecular main chain repeating units containing amide groups in the polymer of the general term. Is the five engineering plastics in the production of the largest, most varieties, the most widely used varieties, and other polymer blends and alloys, etc., to meet different special requiremen...

Recently, PEEK material concept stocks continue to ferment. With new energy vehicles, robots, 3D printing and other new downstream requirements for lightweight enhancement, PEEK materials are expected to usher in explosive growth. 1. What is PEEK? PEEK, or polyether ether ketone, is a new semi-crystalline aromatic thermoplastic engineering plastic. Because its molecular chain contains a large numb...

What is PA12-LCF? PA12-LCF is a thermoplastic material, belonging to the nylon class. PA12-LCF is based on nylon 12, which has 12 carbon atoms in each polymer repeat unit. Nylon 12 is also known as polyamide 12 or PA12. It is a semi-crystalline material with a high melting point (180°C) and a low moisture absorption rate (0.5%). It is also resistant to chemicals, wear and impact. PA12-LCF is a mod...

Glass fiber is a very common material in the chemical industry, often used in the production of reinforced plastics or reinforced rubber. Due to Glass Fiber has high temperature resistance, flame retardant, corrosion resistance, heat insulation, high tensile strength, good insulation characteristics, raw materials after adding glass fiber can significantly improve the heat resistance and mechanica...

HIPS and ABS are the first plastic materials used in household appliances, due to the high price of HIPS and ABS resin, the market has gradually developed PP(polypropylene) modified materials suitable for household appliance parts, and partially replaced HIPS and ABS resin in household appliance products with its advantages of low cost, light weight and good performance. Now the modified PP plasti...

Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...
