Shanghai Jinyuan Plastic Products Co., Ltd. plastic products design process, there are some basic factors that can not be ignored. Manufacturers of raw materials can be said to be an important driver of plastic products design, product design process of material selection, process selection, considering strength, mold design and other aspects need to pay attention to what? Plastic product design basic skills and principles of what? Enterprise has been the focus of attention, today's Shanghai Jinyuan Plastic Products Co., a detailed summary for everyone to share:


(1) Design Checklist
Target new product development or product improvement is to make our products have excellent performance, while achieving lower production costs. Design tasks including selection of raw materials, selection of processing methods, strength calculation and mold design. Only thorough consideration of these factors, and systematic follow-up, in order to produce high-quality, commercially-effective mold. It must be emphasized that the practicality and cost-effectiveness of the plastic is not inevitable, designers must pay attention to the correct solution very selection of raw materials and machining process.
(2) Comparison of raw materials
Compared with other traditional materials, the need to pay special attention to the design of plastic parts when raw. Properties of the plastic can be varied over a wide range. By adding fillers, reinforcing materials and modifiers, by its nature will have a great conversion. Sometimes under the same operating conditions, the plastic and metal will be showing a completely different performance. Therefore, the metal casting cost-effective functional design, if hastily used in plastics, will easily fail. When the material temperature closer to its melting point, temperature and time will be a direct impact on the performance of the raw material deformation. Properties of the plastic is not only the nature of pure raw materials. If the processing of raw materials in a range not applicable, even the best design will fail. Similarly, the product does not control the process to resolve design weaknesses. Therefore, only take into account all the factors of the optimization process in order to ensure the quality of plastic parts.
Location (3) of the gate
Designers not only to calculate the design of plastic products, we must also pay special attention to the mold gate design. They must select the correct gating system and the number and location of water points. Quality gate type and location of different products will have a greater impact. If the designer chooses the wrong gate, almost impossible from the optimization of processing parameters to correct the resulting consequences molding.
(4) Basic assembly technology
Some designers recognized all simple assembly techniques such as snap-fit, screw press assembly and assembly, its simple and quick assembly components can greatly reduce production costs. The biggest advantage is the snap-fit ​​assembly does not require additional components. In the buckle design, the designer must ensure that the parts of geometry, to avoid the stress relaxation caused by loose parts assembly. Presser assembly allows the assembly of high-strength plastic components at the lowest cost. Threaded mounting by the use of separate type, screw-type or a combination of the overall composition of the screw inserts. To avoid defective components, ensure the correct size of the sleeve is a key part. Screw fittings manufacturer may make a number of proposals in this regard.
(6) Materials selection
In general, no bad material, and only in specific areas using the wrong material. The most commonly used in injection molding of thermoplastics. It can be divided into amorphous and semi-crystalline plastics plastics. In general, the semi-crystalline thermoplastic is mainly used for parts of high mechanical strength, without shaping thermoplastics due inflexible, it is often used in the housing. There unreinforced thermoplastics, glass fiber reinforced, mineral filled vitreous and other types of products. Glass fibers are mainly used to increase strength, firmness and improve application temperature; mineral and glass with the lower reinforcing effect, mainly used to reduce warpage. In some thermoplastics added a series of reinforcing materials, fillers and modifiers to alter their properties. Some thermoplastics, especially PA6 and PA66, very hygroscopic. This could have their mechanical properties and dimensional stability have a greater impact. During, should pay special attention to this performance.
(7) Cost saving design
The final cost of plastic parts designers bear most of the responsibility. His decision in advance determines the cost of production, mold making and assembly. Correction and optimization of late is usually expensive and not feasible. Give full play to the advantages of plastic material properties, cost savings in many ways. In-one design, the use of low-cost assembly technology (such as snaps, welding equipment, fixtures, double injection technology, etc.), the use of self-lubricating characteristics, obviating the surface treatment procedures. Note that the wall thickness, mold, tolerances, and other raw materials to further cost savings.
