Plastic injection molding mould usage and maintenance

As a mould manufacturer, we have many years experience In mould correct usage and mould maintenance.

Firstly, we need to choose a suitable injection machine, plastic injection mold design is made by plastic injection machine. We need to choose one injection machine satisfied the plastic injection mould production, such as injection machine capacity, clamping force, injection pressure, distance between tie-bras, and mould thickness. We need to check if this information is fitting for the mould and machine.

Secondly, we need have professional engineer to put the mould on the machine and assemble the mould correctly.

Thirdly, in products molding condition, we need to choose small clamping force ,injection pressure and the lowest mould temperature and low material flow.

Fourth, when adjust the machine ,we need to adjust slowly to avoid the mould damaging.

Fifth, when mould stripper the products, we need to adjust the action process, speed and stripper pressure. We need to consider the product appearance.

Sixth, usually, the mould temperature should be check if it is in the required range.

Seventh, when we pick the products out, we need to keep the mould cavity clean, no oil and no waste material.

Any further question, please feel free to contact me.

Steel material treatment

As we all know, in plastic injection molding area, steel material treatment is one of the important factor for plastic injection mould manufacturing, which will effect mould life, mould usage and so on.

Today, let us discuss about mould material treatment:

Heat Treatment : heat treatment is a technology changing material physical property by the heating and cooling. Heating treatment can change steel structure inside, and transfer it to required physical property. The tenacity, hardness and abrasive resistance of the material will be improve or reduce. Heating treatment is including Tempering, Annealing, surface tempering and so on. Such as H13, 2316, usually ,we use heat treatment for this material.

Hardening : hardending is a technology that heat steel material to a certain temperature, after set heat-keep time, cooling with oil, water, salty water and any other liquid medium. The main aim is get a thing after dealing with the steel and improve the steel material strength and hardness. For example, usually 718H material need to pre-harden before tooling.

Any plastic injection molding steel material need to discuss, please feel free to let me know. We not only offer clients plastic injection mould or machine ,we offer clients full set of plastic injection molding solution.
