In the plastic manufacturing industry, the plastic injection machine holds primary importance. Your entire production will be dependent upon the machine you are buying. If you have been able to buy the best quality machine, the efforts of your workmen will come to fruition. You will be able to see the visible results in your profit margin.

1. Avoid buying used machines

When would you sell a machine? When you are either shifting from one place to another and you are unable to carry it with you, you may sell the machine. However that occurs rarely in the case of injection molding machines because manufacturing units do not shift that frequently. The other reason why people usually sell machines is because the machines are not working perfectly. So, when you find used injection molding machine it is better to avoid it. That is because there are high chances that the used plastic molding machine is not working well.

2. Avoid buying large screw diameters

A lot of China injection molding machine suppliers and factory manufacturers avoid buying large screw diameters in molding machines. The plastic material will tend to take more time for heating when the large screw diameters are used along with small shot sizes. However, if large shot sizes are used, the barrel heaters will be able to speedily heat up the plastic material. If the heating up takes too much time, material degradation could occur which could in turn cause issues with the quality of the material. The material quality could get further degraded because of the large shearing force that is generated in the screw rotation process.

3. Limit in the injection pressure

When you are buying a plastic molding machines, make sure that there is no limit in the injection pressure. That is because it will effect quality of the plastic material if there is any limit to the injection pressure. It must have minimum 10% reserved injection pressure which will facilitate the machine to adjust automatically to the normal variation of the material viscosity.

When buying a plastic molding machine from an injection molding machine supplier, check the clamp tonnage. It must be adequate for your machine as it will affect the quality of the material.
