I want to produce products with high precision, customers reflect the products do not need to buy more stable, precision injection molding machine, injection molding machine is now used in the production of Haitian sword, how to judge the accuracy of horizontal injection molding machine production? What are the indicators to see?
The product size is usually controlled by injection pressure / pressure, injection volume, holding pressure / time. The selection of injection molding machine mainly depends on the control of the main parameters of "pressure, speed and temperature".In addition, the product size instability, not only related to equipment, and mold injection molding technology also has a lot to do with parts and materials also related, you should analyze the reasons in many ways.
General precision injection molding machine has two indicators: - is the product size repeated error, and the other is the repeated weight error of the product. The former is difficult to compare because of the size and the thickness of the product, and the latter represents the comprehensive level of the injection molding machine manufacturers. Repeat error weight like ordinary injection molding machine in 1% or so, the better machine can reach O.8%, less than 0.5% of the precision machine, less than 0.3% for ultra precision machine, reported the highest international level is less than O.15%.
This is more complex, the general precision injection molding machine has two indicators: - is the product size repeated error, and the other is the repeated weight error of the product. The former is difficult to compare because of the size and the thickness of the product, and the latter represents the comprehensive level of the injection molding machine manufacturers. Repeat error weight like ordinary injection molding machine in 1% or so, the better machine can reach O.8%, less than 0.5% of the precision machine, less than 0.3% for ultra precision machine, reported the highest international level is less than O.15%. Precision injection machine precision requirements of the products within 0.01 ~ 0.001mm, many also require precision injection molding injection molding machine with high injection pressure and speed requirements; the clamping system has enough rigidity and clamping precision; required precise control to the corresponding precision of pressure, flow, temperature and measurement parameters; using multi-stage or stepless injection; ensure the reproduction condition and molding process of the repeat accuracy etc.. The repeated weight precision of injection molding products reaches stability, which includes 3 aspects: repeatability of plasticizing quantity, repeatability of injection quantity and temperature control performance of mould. And the impact of these accuracy and many, the most important injection molding machine manufacturing and assembly accuracy, as well as injection molding machine screw, electrical, hydraulic and other original configuration of the good or bad, the quality of the mold and so on. As you mentioned is low with the Haitian Haitian Tianjian, and MA Tianlong series, and all electric better, to see your product requirements.
1, general precision injection molding machine has two indicators: - is the product size repeated error, and the other is the repeated weight error of the product.2, the former because of the size and product thickness is difficult to compare, and the latter represents the injection molding machine manufacturers comprehensive level.

And the impact of these accuracy and many, the most important injection molding machine manufacturing and assembly accuracy, as well as injection molding machine screw, electrical, hydraulic and other original configuration of the good or bad, the quality of the mold and so on.
