PP injection molding process/Long Fiber reinforced Thermoplastics PP Polypropylene Melt temperature: 240-250℃ Barrel constant temperature: 220℃ Mold temperature: 60-100℃ Injection pressure: 100-160Mpa, if it is a long runner product with thin wall thickness, it needs to reach 180Mpa. Holding pressure: 50% of the injection pressure. Since the material condenses relatively quickly, a short holding time is sufficient. Properly reducing the holding pressure can reduce the internal stress of plastic products. Back pressure: 2-8Mpa, need to be accurately adjusted according to the specific product, because too high back pressure will cause uneven plasticization. Long Fiber reinforced Thermoplastics PP Polypropylene/sale02@lfrtplastic.com/Ms Amy chan Injection speed: It is recommended to use a relatively fast injection speed; otherwise the product is prone to coking; Screw speed: The screw speed is high, it is recommended to set the screw speed lower, as long as the plasticization process can be completed before the end of the cooling time; Measuring stroke: 0.5-3.5D Residual amount: 2-6MM depends on the measuring stroke and screw diameter; Pre-drying: drying at 90℃ for about 4 hours. Nylon has water absorption and should be stored in a moisture-proof container and a closed hopper; water containing more than 0.25% will cause molding changes. Recovery rate: 10% recycled material can be added/Virgin Long Fiber reinforced Thermoplastics PP Polypropylene Shrinkage rate: 0.7-2.0%, if 30% glass fiber is added, the shrinkage rate is probably in the range of 0.3-0.8%, pp long glass fiber 30% provides a temperature exceeding 60 ℃, the product should be gradually cooled; gradually cooling can reduce the molding shrink. Nylon products can be checked by welding flux. Gate system: point type, latent type, sheet type and straight gate can be used; it is recommended to use blind holes and gate grips to obtain cold material points; hot runner can also be used due to the narrow processing temperature range of the melt, it is necessary to provide closed loop Temperature control./sale02@lfrtplastic.com;/Ms Amy chan Barrel equipment: standard screw, special geometric size has higher plasticizing capacity; for glass fiber reinforced materials, long galss fiber PP reinforced thermoplastic Polypropylene requires high wear-resistant bimetallic barrel; Machine shutdown period: no need to clean with other materials; the residual material can be degraded by subsequent thermal dissolution; sale02@lfrtplastic.com;Amy Virgin Long Fiber reinforced Thermoplastics PP Polypropylene

Wheelchairs are an important tool for rehabilitation. Wheelchairs are just a means of transport for physically handicapped and people with reduced mobility. What's more important is to make them physically exercise and participate in social activities. Ordinary wheelchairs generally consist of a wheelchair frame, wheels, brakes and a seat. The hand-cranked wheelchair is based on an ordinary wheelchair and adds a hand-cranking device. The electric wheelchair adds an electronic power assist system based on the ordinary wheelchair, which reduces the user's intelligent wheelchair based on the electric wheelchair, and increases positioning movement, narrow movement, remote control movement and related Internet + assisted living. When looking for a lightweight wheelchair, you should check the materials used in the wheelchair and the continuity of the material. More importantly, the weight of the material. The most common material is stainless steel. However, the problem with stainless steel is that it can be heavy. Therefore, the recommended material PP lgf20-60%. The Xiamen LFT composite plastic Co.,ltd factory manufactures long fiber reinforced thermoplastics using a proprietary pultrusion process. It can be customized and customized with 20-60% PP long glass fiber material and added with corresponding additives. Due to the high strength-to-weight ratio, PP lgf20-60% manufactured by Xiamen LFT Composite Plastic Co., Ltd. is a wheelchair wheel and other applications. An excellent material choice, wheelchair wheels must withstand extremely high stresses over a range of temperatures. *Long-term heat resistance *Low VOC / odor release *UV protection;

The car's rearview mirrors are located on the left and right sides of the car's head and in front of the car's interior. The rear view mirror reflects the rear, side and underside of the car, allowing the driver to see the position indirectly. It acts as a "second eye" and expands the driver's field of view. The car rearview mirror is an important safety piece, and its mirror, shape and manipulation are quite elaborate. The quality and installation of the rearview mirrors have corresponding industry standards and cannot be arbitrarily. The rear view mirror frame acts as a stand. The choice of materials needs to consider the outdoor anti-aging factors. PP Polypropylene add 50% long glass fiber is recommended for your reference. Although ABS TPE PA raw materials are usually used, some customers even try to use MXD6 raw materials. PP Polypropylene add 50% long glass fiber After adding the corresponding anti-UV, it can perfectly meet the performance requirements of the product.

Modern people are increasingly enjoying a variety of challenging sports. Especially in some western countries. Skiing is a popular item. More and more amateurs will organize the sport themselves. The use of skis is becoming more and more popular. During the taxiing process, the uneven surface conditions, the height and weight of all types of people, and the requirements for skiers will be higher and higher. After testing a part of the material of PA Polyamide Nylon 6 with long galss fiber40, a German ski manufacturer can test the tensile strength of the product to reach their required 170-180Mpa or higher, anti-fatigue, wear resistance, etc. Performance also meets the demand; in the inspection of parts, they are more concerned with the type of manufacturing process different from metal materials, injection molding can make their products have better shape, size and design performance. In addition, LGF long glass fiber reinforced PA6 has a lower specific gravity than metal materials, which also reduces the weight of their products and makes the products lighter. Long Fiber's LGF long glass fiber reinforced PA6 material is a modified reinforced composite material obtained by adding different lengths of glass fiber to the nylon PA6 matrix material and modifying it by certain production techniques. We believe that through the joint exploration with customers, PA Polyamide Nylon6 with 20-60% Percents materials will have more breakthrough applications in the field of sports equipment.
