It is not difficult to choose a vertical injection molding machine

Many people have been complaining that they do not know how to choose their own vertical injection molding machine, in fact, vertical injection molding machine to choose accurate is not difficult, let the following Xiaobian to teach you how to choose vertical injection molding machine.

Choice of supplier to the choose and buy of vertical injection molding machine, it is best to choose a nearby service manufacturers purchase, because the vertical injection molding machine structure is complex, hard to avoid is not a problem, quick after-sales service is the key, don't seek low prices when purchasing, injection molding machine accessories, now domestic and import price difference is very big, so you need to try to find out the manufacturer use what brand of accessories. Of course, you can't see some parts, such as oil seals, bearings, etc., so at this time the visibility and credibility of the manufacturer is very critical.

How to choose a vertical injection molding machine

Usually, the important factors affecting the selection of injection machine include mold, product, plastic, molding requirements, etc. Therefore, the following information must be collected or obtained before the selection: mold size (width, height, thickness), weight, special design, etc.; The type and amount of plastic used (single material or multiple plastics); The appearance size (length, width, height, thickness) and weight of the injection moulded products; Forming requirements, such as quality conditions, production speed, etc.

1, get: by the mold and finished product determination “ Die opening stroke ” And & other; Die stroke ” Is it sufficient for the finished product to be removed? The die opening stroke shall be at least twice the height of the finished product in the direction of the switching die, and shall include the length of the vertical sprue. The supporting stroke should be sufficient to eject the finished product.

2, choose the right type: by the product and plastic to decide the type and series.

3. Good shot: judged by plastic “ Screw compression ratio ” And & other; Injection pressure ” Such conditions. Some engineering plastics need high injection pressure and suitable screw compression ratio design, only to have a better molding effect, so in order to make the finished product shoot better, in the selection of screw also need to consider the injection pressure and compression ratio.

4, put down: by the size of the mold to determine the machine “ Large column spacing ” , & other Die thick & throughout; , & other Mold minimum size ” And & other; Dimension of die plate ” Appropriate to confirm whether the mold will fit.

Vertical injection molding machine classification

1. Classification according to the closing mode 1. Mechanical 2. Hydraulic 3. Hydraulic & ndash; — mechanical

Two, according to the way of plasticizing classification

1. Plunger type plastic injection

Molding machine its mixing is very poor, plasticization is not good, to add a split shuttle device. It is seldom used now.

2. Screw & ndash; — Plunger type plastic injection molding machine depends on the screw for plasticizing and depend on the plunger for injection, the two processes are separate.

3. Reciprocating screw plastic injection molding machine; Rely on the screw plasticizing and injection, mixing and plasticizing are very good, now the most used.
