How to order a good plastic chair mould? Most plastic mould manufacturers can produce plastic chair moulds. But to produce high-quality chair mould, we know that there are not many companies. If you want to know the quality of the chairs they produce, please ask the plastic mould company the following questions:

  • Chair mould cycle and service life
  • Is the wall thickness of the plastic chair uniform?
  • How about chair stacking?
  • How to design the seatback exhaust?
  • How to improve the chair mould durability?

How to judge the moulding cycle of the chair?

  • If the cooling water temperature is 8-12 degrees and the weight of the chair is 1700g to 2400g, the period should be 35s-50s.

How to ensure the longevity of the plastic chair mould?

  • You need to check the hardness of the steel and whether the mould has welded parts. Normally, the hardness of steel should be HRC33.

Is the wall thickness of the plastic chair uniform?

  • Most of the reasons are the poor lighting of the 3D design of the plastic chair and the cavity core. Therefore, when we begin to design the plastic chair mould, we must consider the wall thickness coefficient. Sometimes we need to increase the thickness in certain areas to ensure the strength of the chair.

How about chair stacking?

  • When starting the chair mould design, we must check its superimposed effect. At the same time, you must consider the possibility of deformation of the chair shape.

How to design the seatback exhaust?

  • The back design of some chairs is complicated because there are many plastic welding that can cause poor exhaust when the material is filled and flowed. Therefore, you must use mould flow to analyze whether you need to vent certain areas of the plastic chair mould.

How to improve the chair mould durability?

  • In order to prevent the mould cavity from being corroded by the plastic, you must ensure that the steel is chrome-plated and the hardness is greater than 33. If some recycled materials are used, the plastic chair mould must be chrome plated. Otherwise, the mould should be polished frequently.
