How to Maintenance Plastic Injection Mould

In order to ensure the plastic injection mould work normally, smoothly, lower trouble and prolong the using life of machine, user must note to maintain the mould during everyday use.

 

Sino has rich experience in how to maintain plastic injection mould, since we are not only Chinese famous injection mould supplier, but also injection molding company. We know every detail of mould and molding process so had accumulated rich experience in maintenance plastic injection moulds. Below are our common methods, for your reference:

 

After finishing mass production, we need to check the mould in a complete inspection.

1. We should check and clean both parting surface, ensure that the cleanness of the mould.

2. Check the mould runner to ensure there is no defective material in the runner.

3. Clean venting-groove.

4. Cleansing cooling channel with PURE & sanitary Liquid, then pulling away leftover by air gun & drying channel via SIROCCO.

 

While in the daily mould maintenance, we also need to check the whole parts of the plastic injection molds, like the safety pin, safety screw, side guard and so on.

1. Check and test cooling channel on airproof guard.

2. Measurement of heating system under H.R. Instruction.

3. Ensuring Hydraulic C. moving under proper Conditions and w/o Oil-leak Problem.

4. Adding enough Lubricant for smooth core pulling movements.

5. Make sure lubrication of the sliding mold parts.

6. Measure hydraulic system’s pressurization.

 

Mould storage: after all techniques finished, physical dryness &antirust treatments are required according. Finally, fixing & storing mould under dry conditions.

 

Please keep in mind if we keep maintain well of the molds, the mold will become the longer life. If you are newer investor in plastic injection industry who is not professional in such industry, please kindly contact us when you have any problem, we are glad to reply you and help you with your business.

Demoulding Way for Crate Moulds

There are two common demoulding ways of crate mould, one is latch locking system, another one is hydraulic cylinder system.

Below is short analysis of these two demoulding systems.

For latch locking system, when mould opens, the latch lock pulls the slides to demould, which lead to short cycle time, high efficiency, so lots of customers prefer such system. Howere, compare with hydraulic cylinder system, latch locking system has short mould life. So Sino pay high attention in lengthening the mould life of latch locking system, and has accumulated rich experience. We make inserts between latch lock and slides, if the insert was broken, it is easy to make and change. Usually, we adopt high hardness and wear-resisting steel to make inserts, and send extra inserts to customer. Latch locking system has short cycle time, so the crash pressure on parting surface is large, so we add buffer gasket or spring under stripper and slides to reduce the crash pressure.

If customer want to make thin-wall crate mould, we suggest adopt H13 or DIN1.2344 steel for core and cavity since thin-wall crate has strict required on steel hardness. The thickness of thin-wall crate is less than 1mm, when injection, the injection pressure is very large, and the clamp tonnage also large, so the steel must be hard enough to avoid deformation. Otherwise, product will has flash after long time squeezing.

For hydraulic cylinder system, it is much stable than latch locking system, since it uses oil pressure to control demoulding speed. And hydraulic cylinder is not easy to break, so its mould life is longer than latch locking system, but its cycle time is longer.

If you want to develop crate mould, and want to know more about techincal points, pls feel free to contact with me, I will offer best solution for your project.

Thin-Wall Container Molding Line

DKM has accumulated rich experience in helping customer establish various plastic molding factories, especially thin wall container molding factory. We can not only design and manufacture high quality thin wall container molds, but also provide special machine, robot and necessary auxiliaries to help our customer achieve excellent production capability at fraction of costs. Until now, we have accumulated many advantages in thin wall container production line:

First, to thin wall container, the most important factor is thickness, the thinner, the better, because it leads to material cost and cycle time. So our experienced engineering team spent many years on trying to cut down the thickness to 0.28mm, finally we made it. 

Second, short cycle time, our designers will analysis the product according to customer requirements, then try to figure out the best water channel before mold tooling. We also use cu-be on the bottom of the core to make each cavity cool quickly. What’s more, our experienced engineering team developed high speed injection molding according to thin wall box mold features. For example, 0.28mm thickness, 0.5L, 4 cavity molds, the cycle time is 3.5s.

Third, we can offer customer IML technology according to their requirements. IML products are more attractive and easier to be remembered by customers, so more and more customers want to make IML container mold. In order to help customer save labor cost and improve the production efficiency, we also can provide suitable robot per the mold and injection molding machine.
