How to make Plastic Crate Mold with long mould life?


As one of famous crate mold manufacturer in China, plastic crate mold is our first important featured product on plastic injection molds, we made around 100 sets of crate molds every year, including milk crate mold, beer crate mold, coca cola crate mold, vegetable crate mold, plastic box mold, auto parts box mold, fruit crate mold, beverage crate mold, logistics box mold, battery box mold, storage box mold, industrial box mold, turnover box mold, fish box mold, etc.

How to make plastic crate mold with long life is very important for all plastic crates manufacturers.

Now, we help you to solve the problem.
At first, Good Mold Design and Good Mold Structure:
The qualified mold must have perfect mold structure before start the project. So we spend a lot of time on analyzing crate mold structure and mold designing, including demold draft angles, the epitome of product surface, gate system design, air exhaust problem, cooling system design, hot runner balance problem, etc. In order to increase cooling performance, we use special design on the water channels for core and cavity of mold.The main problems that may easily occur will through trial and error during the mold structure design.

Secondly, Good Mold Steel
In order to improve the mold life and product quality, we should increase the mold steel hardness through heat treatment. The steel which we are commonly used with P20H, 718H, H13, or 2738. The four sliders are always nitrided to increase the hardness. In order to improve the cooling effect, beryllium bronze will be inserted on the top of core, surface of sliders, or cavity.

Third, Good Cooling system
Cooling system design is quite difficult work, consider the uniformity of the cooling and the cooling effect, also the impact brings to the overall mold structure, determining the exact location and size of the cooling system; and cooling for key positions such as moving plate or the inserts, side sliders as well as side cores; standard cooling element design and the selection of the cooling standard components.

ACE MOULD analyzes all series of factors when begin to start the mold design. The mold has recycled water to flow in every part of it which reduces the cooling time, improves the production efficiency and greatly reduces products costs.

The water cooling system is very important. We adopt single loop cooling lines and setup even distribution water channels as much as possible.

Last one, Good Maintenance

It is also very important to keep maintenance for the plastic molds as well. We should check and make sure the water channels and air circuit unlocked after a period of time using. Add lubricant oil for the sliders, clean the stripper plate during production. You must clean the mold and sprinkle the antirust agent after stop prpoduction.If you have any problem on the crate molds or on plastic crates molding, try to contact us and we will help you to solve.
