Craft of principle of plastic storage rack is classified

Note model

Classification of craft of principle of plastic hardware storage rack is a kind of method that makes plastic product, melt plastic use pressure to note in taking plastic products pattern, refrigeration shapes get wanting all sorts of plastic, apply to a quantity the product with big, expensive precision, mould price inspects particular case to differ. The appearance of earning often is final finished product, need other treatment no longer before install or be used as final finished product. A lot of detail, be like raised ministry, costal region, whorl, can injecting moulding shapes in one pace operation come out.

Note model to shape multi-purpose at thermoplastic plastic. It and crowded model shape similar, what what differ is melt what plastic classics nozzle enters is to close inside the mould, caky inside the mould shape and get product. Noting model opened a mould to be shot, intensity is high, wear of colour and lustre is good and standard of edges and corners, can make thicker product.

Suck model

Sucking model is will plastic sheet after heating, pass a mould, be in in vacuum action, the appearance of inspiratory mould, cooling shape, apply to a structure to compare the product with simple, little quantity, the mould is cheaper. Its cost is cheaper than noting model, yield is high, the mould is bit cheaper also. Suck model to basically be used at thin wall goods for many, with long colour and lustre changes likely, but not certain also, additionally crop is like also relatively note model to want big, and what the production such as relevant water mouth produces waste material also compare little.

Blow model to also say hollow blow model

One kind develops swift plastic treatment method. Thermoplastic colophony goes out via squeezing or inject shapes gotten tubal written complaint is plastic model base, take the advantage of heat (or heat bate condition) , park runs from opposite directions in the model, after shutting a model, be in instantly model connect inside base compress air, make plastic model base huff and clingy go up in mould wall, via cooling drawing of patterns, get all sorts of hollow product namely. The workmanship of the film that blow model blows model with hollow goods on the principle very similar, but it does not use a pattern, from the angle that plastic processing technique classifies, blow model to shape filmily craft includes normally crowded in going out. The craft that blow model is during the Second World War, begin to be used at producing pyxis of low density polyethylene. Among them basis base makes a method, blow model to be able to be divided go out to squeeze blow model and inject to blow model, new development rises have multilayer blow model and drawing to blow model.
