When we need to purchase a vertical injection molding machine
, we should be how to choose the precision of vertical injection molding machine, due to the vertical clamping vertical shoot glue, lower die fixed upper die activity.
Straight way of injection molding machine is embedded in a plastic injection molding optimization scheme, the following is to introduce the injection molding machine factory about vertical injection molding machine and model classification factors of choose and buy.
Selection of injection molding machine is the most basic four elements: a, molar volume, both mould length * width * height, choose suitable for factory specifications of the product mould and slightly bigger than the mould, for elder brother Lin Zhu within the effective distance;
Second, the injection quantity, average is calculated on the plastic PS, unit for an ounce (
, because of PS density ratio is a vertical to 1 cm.
5 g, this is a conventional calculating unit.
Different plastic for structure density than is different, so choose products turnning water mouth contrast injection molding machine is the most effective injection amount is not greater than 80% and not less than 20% for models;
Said three, the product precision, the accuracy of the plastic product is directly related to the choose and buy of the machine and configuration requirements, such as engineering plastics must choose alloy screw and feed tube, screw length to diameter ratio L/D more than 20 times more, can achieve good plasticizing standards and requirements.
Should product precision requirements can choose specific pressure + than flow or half closed loop type or full closed loop circuit control, etc. ;
Four, the clamping force for injection molding surface is the most crucial part of the clamping force per tons of said unit (
, the selection of the clamping force standard to plastic products in different length * width * plastic working resistance of the classification of vertical injection molding machine, vertical injection molding machine specific vertical injection molding machine can be divided into the following categories 1, series: the aircraft mainly for cable, all kinds of electronic, computer cable and power plug line, such as injection molding, injection molding products accurate standard is not high, generally dominated by PVC, PE and other plastic injection molding, suitable for the concrete suitable model of the product specifications generally clamping force ranging from 15 t - to 35 t, because of each manufacturer of molar volume, specific configuration are different, before the choose and buy must require manufacturers to the factory to determine the specific parameters of the model specifications, etc.
2 C injection molding machine, vertical injection molding machine, series: this machine is vertical clamping, horizontal beam glue because there was no guide pin, due to the clamping part into a letter & other;
Words, the name.
This machine structure is complex, with super glue, because there was no guide post work area is broad, mainly is suitable for engaged in all kinds of safety power plug injection molding, such as France, American plug, the plug.
3, vertical single board type injection molding machine, double slide type series injection molding machine: this machine mainly in view of the engineering plastics, the precision of the products have strict requirements, precision or have small insert molding together, it is also one of insert the optimization of injection molding solution.
Because the machine has a fixed upper die, die sliding out function.
On the double slide type has a mode under the dual mode, two alternating mold, compared with is suitable for precision hardware embedded in or out.
General molding products, such as electronic connector, mobile phone connector, IC components such as atlas air compressor accessories.
4, vertical injection molding machine, rotary disc type series: series vertical rotary disc type injection molding machine is precision embedded injection molding optimization scheme, because the machine can design more than one upper die two lower die or mould function, compared with suitable for complex embedded and the advantage of labor savings.
More information about how to choose the precision of vertical injection molding machine is knowledge of injection molding machine factory finishing for everyone, hope that the above contents are helpful to you.
