Choosing the right injection molding machine is one of the most critical criteria to continuously create efficient machining parts.
The right machine will help keep it low and improve your productivity.
This will allow you to sell more parts and make more money while building a position for a reliable company.
Better yet, you will have long-term customers.
Another important criterion for manufacturing efficient and high quality parts is the selection of high-quality mold designs.
How to keep low cost?
A carefully selected casting machine will provide you with the above points.
Here are some of the most common machine selection errors and their impact the most effective way to evaluate the importance of correct machine selection is to list the most common faults when selecting a machine and the productivity and conditions for parts.
Error 1: the key to buying a used injection molding machine that is not working well to buy a reliable second-hand machine is to look for a machine that has been fully checked before delivery, this way you will not suffer production losses many times due to the following reasons
Error 2: Select the large screw diameter.
Sometimes, the large screw diameter can cause quality problems due to lack of material.
When using small lens size and large screw thickness, the plastic material needs more time to be heated by the barrel heater compared to the large lens size.
Material deprivation is more likely to occur if the shooting size is too small compared to the maximum shooting capacity of the injection device, especially for thermal materials.
Another difficulty with the thickness of the large screw is the large clamping force generated during the screw rotation, which may also destroy the material and may result in the rejection of the part. Mistake 3: All-
The main benefit of the purpose scream is-
The purpose screws can be used with most plastic materials such as PE, PP, PET, nylon, and PC, so their adaptability is very strong and very good for the molding company that forms various materials.
The downside is that for some materials, the component type and efficiency will be lower compared to more advanced injection casting screw designs such as barrier screws.
Error 4: injection pressure control molding technology for continuous manufacturing of efficient parts should not be limited by injection pressure.
It is recommended to set aside at least 10% of the injection pressure so that the injection molding machine can automatically adjust to the normal change in the thickness of the plastic material.
A smaller injection pressure creates a short molding.
Typically, the injection unit screw thickness controls the maximum injection pressure available, so it is important to choose the right diameter when purchasing a plastic injection casting machine.
