Matters Needing Attention in Using Crate Mould

1. The steel used for making die parts of Crate Mould(FURNITUREMOULD) shall be wear-resistant, corrosion-resistant, with small deformation in high-temperature environment and certain toughness.

2. All parts in the crate mould shall be assembled in the mould body, and the cavity working surface of melt flow channel formed shall be smooth, level and free from material stagnation. If necessary, hard chrome layer shall be plated on the surface.

3. When the parts in the crate mould are disassembled and the sticky materials are cleaned, it is not allowed to strike the working face with a hammer, and it is not allowed to clean the residual materials stuck on the working face with a scraper, and there are no scratches and burrs on the working face.

4. Pay attention to the process temperature control of each part in the crate mould to meet the requirements of the tube blank forming process, and the mandrel in the large-size tube forming mould to have a heating temperature control device.

5. The center line of each part in the crate mould shall coincide with the center line of the mould body and the screw after assembly.

6. When the forming die is not used for a long time, all parts shall be cleaned up, coated with antirust oil, and sealed at the inlet and outlet for storage after assembly. Heavy objects are not allowed on the stored crate mould body to prevent the mould from deforming.

What Are The Common Problems in The Test of Crate Mould?

If you want to solve the common problems in the mould test of the Crate Mould(FURNITUREMOULD), you have to know where the problem is in order to solve the problem. Let's talk about some common problems in the test of crate mould.

1. The main runner die bonding

The solution to the problem is to polish the main runner, with the nozzle coinciding with the mould centre, reduce the temperature of the crate mould, shorten the injection time, increase the cooling time, check the nozzle heating ring, polish the surface of the crate mould, and check whether the material is contaminated.

2. Difficult demoulding of plastic parts

The solution to the problem is to reduce the injection pressure, shorten the injection time, increase the cooling time, reduce the temperature of the crate mould, polish the surface of the crate mould, increase the demoulding slope and reduce the gap at the insert.

3. Poor dimensional stability

The solution to the problem is to change the temperature of the charging barrel, increase the injection time, increase the injection pressure, change the screw back pressure, increase the temperature of the crate mould, reduce the temperature of the crate mould, adjust the feed amount, and reduce the return ratio.

4. Surface corrugation

The solution to the problem is to adjust the feeding amount, raise the mould temperature of the crate, increase the injection time, increase the injection pressure, raise the material temperature, increase the injection speed, and increase the size of the sprue and gate.

5. Plastic warpage and deformation

The solution to the problem is to reduce the crate mould, reduce the material temperature, increase the cooling time, reduce the injection speed, reduce the injection pressure, increase the screw back pressure and shorten the injection time.

Why Should The Crate Mould Be Tested?

The defects of most crate products are caused during the plasticizing and injection stages of the Crate Mould(FURNITUREMOULD), but sometimes they are also related to unreasonable design. The influencing factors include the type of injection port, the number of mould cavities, location and size, the design of the cold/hot runner system, and the structure of the product itself. Therefore, in order to avoid product defects caused by the design of the crate mould, we need to analyze the crate mould when making it.

After the test results of the crate mould, the operator usually needs to re-evaluate the specific conditions of the crate mould to avoid unnecessary cost and time in the process of modification. In most cases, in order to make up for the deficiencies in the die design of crates, the operator may make incorrect settings without knowledge, because the parameter setting range required to produce qualified products is very small, and any deviation in parameter setting may lead to the quality of the final products far beyond the allowable error range.

The purpose of the mould test of the crate mould is to find out the optimized technological parameters and the design of the crate mould. Not just to get a good sample. This is very important. Even if factors such as materials, machine settings or environments have changed, a stable and uninterrupted mass production environment can still be ensured.
