in order to ensure that the products can be designed reasonable and economic, at the early stage of product design, in appearance designers, engineers, drafters, mould maker, forming factory and material supply factory close cooperation between is a must, because without a designer, can have such a broad range of knowledge and experience at the same time, the obtained advice from different business point of view, the basic premise of the product will be rationalized.
reasonable design product design rules should be on the premise of guarantee product necessary function, make the lowest manufacturing cost. （ 1) Must meet the requirements of customer to product function and service. Engineering machinery to provide customers not only the function of the product, also including support for these features of after-sales service. So in the process of design should not only according to the characteristics of the different function of products and to make the product has good maintenance convenience.
( 2) In line with the requirements of society for environmental protection.
( 3) Comply with the principle of technical innovation, pay attention to the protection of intellectual property rights.
( 4) Starting from the actual technological level and production capacity of enterprises, the emphasis on design and process, and the combination of production. Product design is not just design, including process design and production design.
the material selection of
(1), ABS, high liquidity, cheap, suitable for parts strength requirement is not too high, Not directly impact, not the durability of structure reliability tests under part) , such as internal support frame. And is widely used in electroplating parts ( Such as buttons, side keys, navigation keys, electroplating, etc. ) 。
2, PC + ABS: good liquidity, strength is good, price moderate. Suitable for high rigidity and high impact toughness of parts, such as frame, shell, etc.
(3), PC: high strength, the price is expensive, liquidity is not good. Suitable for high strength requirement of housing, buttons, transmission frame, lens, etc.
(4), POM has high rigidity and hardness, good fatigue resistance and abrasion resistance, smaller creep and water absorption, good dimensional stability and chemical stability, good insulation, etc. Commonly used in roller, transmission gear, worm gear, worm, driving mechanism, etc.
5], PA tenacity, water absorption, but when the water completely evaporated, will become fragile. Commonly used in gear, pulley, etc. Key gear by the impact is bigger, need to add filler.
[6], PMMA has excellent transmission of light, in the light of accelerated aging after 240 hours can still through 92% of sunlight, ten years are still about 89% outdoor, uv, 78. 5%. High mechanical strength, has a certain cold resistance, corrosion resistance, good insulation performance, dimension stability, easy to shape, quality, and the brittle, used to have a certain strength requirement of transparent structure, such as window lens, remote control, such as pieces of light.
product test every design must be in the prototype stage, accept some test, to check the design calculations and assumptions and the difference between entities. Product when use need to do some test, most can do effective through prototype testing; At this point, in the face of all the functional requirements, design and be able to achieve a complete design review. Simulation using the test would be must start at the stage of product model, and the type of test value, depends on using the severity of the condition was simulated. Mechanical and chemical properties of JiaSuHua speed is often viewed as important project model product evaluation.
plastic design wall thickness should be meet the plastic parts when use the strength, stiffness, insulation, weight, size stability and the relation with other parts assembly, and fills the cavity can make the plastic melt smoothly. Design plastic wall thickness should be reduced as far as possible wall thickness, plastic parts allowed minimum wall thickness is associated with varieties of plastic and plastic parts dimension. Design plastic parts wall thickness as far as possible keep uniform wall thickness, under normal circumstances should keep the wall thickness difference within 30%. In the case of plastic pieces of wall thickness difference is too big, can take the plastic too thick part of the hollow out or the plastic parts is decomposed into several parts and the method of combination to reduce the wall thickness difference. The determination of
draft
draft according to the material ( PP, PE silicone, rubber can forcibly demoulding) , surface state, transparent or not decided parts should draft ( Transparent slope is larger) Factors such as comprehensive.
the shape of the plastic parts design inside and outside the surface shape of injection molding processing products shall be designed to be easily molded, out in the mould parts, as far as possible do not use complex flap side parting and core pulling; So the design of the parts to avoid side concave part. Side core-pulling or disc ( Collapsible) Male die and female die not only raise the cost of mould manufacturing, reduce the production efficiency, and will be leaving burrs on the parting surface, increase after processing difficulties.
