Product Description

How to determine the cycle of mold?

If the temperature of the cooling water is 8-12 ºC, and the weight of the chair is between 1700g and 2400g, the cycle time should be 35s-50s. If the plastic melting and injection molding of the machine is carried out under the action of the accumulator, please check their waterway design, whether the waterway is straight through? Is the direction of the waterway consistent with the shape of the chair?

How to ensure the life of chair mold?
A lot of people will say they can guarantee a million mold shots. But who knows how they guarantee that. Can they guarantee that there is no flash after one million molds run? If you cut the flash manually, I think you can produce 10 million molds with this set of molds. Therefore, you need to check the hardness of the steel and whether the mold has welding parts. Normally, the hardness of steel should be hrc33.

How can you make sure that the parting line of the chair has no sharp edge burr?
The rough parting line on the chair is dangerous. In order to avoid sharp edges, we must pay attention to many aspects in the mold production process
Is the design of parting line of chair mould correct?
Is the cavity thick and core thick enough?
How to process core and cavity? One processing or multiple processing?
Normally we need to process three times. From rough machining to steel hardening, when the steel is hardened, we carry out the second stage of CNC milling. We call this stage semi finishing. Under normal conditions, we will leave a tolerance of 0.3mm, and then when the steel stress is released, we will carry out finishing. The machine operation is very important at this time.
We need to cool it in the area of NC milling.
We must ensure that the depth of each cutting process should not exceed 0.08mm.

The question of superposition
When we start the chair design, we need to check its superposition effect. At the same time, you should also consider the possibility of chair mold deformation.

How to make the chair light and strong enough?
When designing a chair, we should consider its weight and strength. You can make the bottom of the chair strong enough by adding more ribs. What about the seat foot, back and cushion? For this, you need to analyze the strength of each area. In order to make a light chair have good strength, you need to choose PP material with low melt index. But the premise is: the mold must be strong, and injection filling must be feasible, because you are using plastics with a melt index of 4 or a maximum of 6
How to design a good exhaust system on the back of a chair?
The back design of some chairs is very complicated, because there are many plastic fusion joints, which may cause poor exhaust when the material is filled and flowing. So you need to analyze whether some areas of the mold need to exhaust through the mold flow.
