Product Description

The disposable plastic box moulding machine is a molding machine specially used to produce the disposable lunch boxes required by the market. Disposable plastic boxes are not only in high demand but also have thin walls. Based on this feature, ZOWEITE launched a high-speed injection molding machine - disposable plastic box moulding machine, the production cycle time is 5-6 seconds. High-speed injection molding machine-disposable box moulding machine has a stable high pressure and high injection system, which is suitable for molding thinner products. Therefore, ordinary injection molding machines cannot produce the disposable lunch boxes required by the market. The warranty period of the machine is one year, if you are interested in our products, please contact us and we will definitely give you a best price.

Disposable plastic box moulding machine advantage:

1.High-responsen oil electric SERVO system cooperates with linear slide rail to project a rigid support structure

2.Dedicated energy-saving technology design, industry leading role of energy saving effect.

3.Fast and stable injection quality, the machine can ues lower cost raw materials or the same raw material to form thinner products, thus improve profitability.

4.High rigidity mechanical structure design to ensure smooth high-speed operation.

5.Machine synchronous structure and mold design greatly shorten the molding cycle.

Preventive methods for poor injection molding size of plastic lunch boxes:
Reasons for the small size of injection molded parts:

Most substances have the characteristics of thermal expansion and contraction, and the same is true for resins, so the molded product begins to shrink after being molded, and it is cooled until it is equal to the normal temperature, but the problem is that if the final shrinkage is too large, the molding size becomes too small, resulting in a small size defect;

One of the reasons is that when determining the initial mold size, the basic shrinkage rate of various resins is considered and the numerical value is calculated as a reference. The size is smaller than the specification size. Therefore, it is necessary to re-correct the mold in the above situation.

The second is related to the environment at the time of molding. Among these are the dry state of the material, the mixing rate of the reused material, the molding conditions, etc., but the most important thing is the molding conditions, because the mold temperature and injection pressure can make the shrinkage amount. increase, so it is necessary to pay attention.

In general, if the injection pressure is increased, the size of the molded product will become larger, and if the mold temperature is increased, the size will tend to become smaller. In simple and easy-to-understand terms, these are: the size of the molded product, the injection pressure, and the injection time. Proportional; inversely proportional to mold temperature.

In the phenomenon that often occurs in long-term mass production, the waste gas generated from the material during injection accumulates in the mold, so the filling of the material becomes poor and the size is too small. Regarding the content related to the waste gas, the key The problem is that in the injection-molded jingmi plastic, it is impossible to have no defects, because defects are more important issues, so we will have to consider them in detail in the future.

Countermeasures when forming:

Increase injection pressure

Lower mold temperature

Extended injection and cooldown times

Confirm whether the type of molding machine and the mold are suitable

Countermeasures for molds

In the case of new molds, re-machining is not good

In mass production, this kind of situation occurs due to the wear of the mold or the blockage of the exhaust gas. First, the mold is completely cleaned to remove the exhaust gas and then the molding is performed again, and it must be confirmed carefully.

The reason for the large size is not good:

It is the exact opposite phenomenon of undersize defect called oversize defect. Therefore, the content of the bad reason is the same as that of the small size. The first is that the size of the mold is not made correctly, the second is the problem of the forming environment, and the third is that the surface of the mold is acidified and eroded due to the exhaust gas. situation caused by the time.

Countermeasures for large size defects:

Reduce injection pressure

Increase mold temperature

Reduced injection and cooling time

Confirm whether the type of molding machine is suitable for the mold

Mold Countermeasures

Will cause the part to be oversized to be re-corrected
