WHAT IS THE PLASTIC CRATE MOULD ?

A crate mould is a tool or form used in the manufacturing process (injection moulding process) of plastic crate box ,also called turnover box mould .

Crate moulds are typically made of metal or other durable materials,Plastic crate mould often made in H13,718 or 2738 material , which has to go through forging, CNC milling roughing, tempering, CNC milling.... They are designed to give a specific shape and structure to the crate according to customers’ requst . A plastic crate mould would be used to shape molten plastic into the form of a crate with specific dimensions and features,the melf low rate usually can be 1.5-5g /10 min. For example, Fruit crate in most cost effective for the plastic crate with minimum cost. The solution is to change traditional plastic fruit crate into disposable crate mould. This can saving your cost of transport, as well as saving the cost of plastic crate molding parts.

The use of crate moulds allows for efficient and consistent production of crates, ensuring uniformity in size, strength, and design. Different types of crate moulds can be used to produce crates of various sizes,  and for different applications (such as shipping crates, storage crates, or display crates). We Guangchao Mould as a professional crate mould manufacturer ,we supply vegtable crate mould ,disposable crate mould ,bottle crate mould ,milk crate mould,fruit crate mould,fish crate mould,bread crate box and industrial crate mould.

WHAT IS THE PLASTIC CRATE MOULDING PROCESS ?

Given the large size of the crate and the substantial amount of raw materials required, the specifications for the injection moulding machine should exceed 1000g. The injection parameters for the plastic crate mould are as follows: screw temperature should be set at 190-220 °C for the front, 220-240 °C for the middle, and 180-200 °C for the rear, with the nozzle temperature ranging from 170-220 °C. The injection pressure should be between 70-100 MPa. The plastic crate box moulding cycle time typically ranges from 60 to 180 seconds, with injection time lasting 5-10 seconds, pressure holding time of 5-15 seconds, and cooling time of 20-60 seconds.

A plastic crate mould must undergo several processing steps, including forging, CNC milling roughing, tempering, and additional CNC machining operations.

WHAT FACTORS INFLUENCING MOULDING CYCLE OF CRATE MOULD ?

What is the meaning of good crate mould ?

 

-Expensive Price ?

-NO.

We think good crate mould requires 3 foctors :

1. short cycle time .

The time required to complete an injection moulding process is called the cycle time, also known as the moulding cycle. The cycle time of plastic crate mould directly affects productivity, greatly inceasred the production volum .

The hot runner is generally used. The advantages of the hot runner are: 1.Material savings. 2. Improved production efficiency. 3. Long-term cost reduction.A good plastic filling system requires a specialized hot runner system for optimal production of durable crates using low melt index HDPE materials, typically with a melt index of 4 or 6. It's essential to design the cooling system for maximum efficiency, utilizing tempered steel and ensuring effective water circulation.

When operating high-speed injection moulding machines, the injection screw speed should exceed 350 RPM, with many manufacturers employing accumulators to boost melt injection speed. A mechanical automatic ejection system is preferred for smooth operation when the mould opens. Additionally, for various mould types to achieve high-speed performance, precision and accurate guiding components are vital to ensure effective operation.

2. Long life mould.

Crate mould to have long-term production capacity, not short-term supplies.Start by selecting the right materials for the mould base, core, and cavity. For a 4-cavity crate mould, use pre-hardened steel with a hardness of over 33 HRC and appropriate standard mould parts. It’s essential to control the hardness of each steel component, ensuring they are not overly hard. The friction and guide surfaces should be finely finished, avoiding manual processing. Additionally, when using recycled materials for plastic injection, it’s crucial to prevent impurities from damaging the core and cavity and to ensure contaminants do not enter the mould.

3.Good exhaust system in crate handle part .

The exhaust system for the plastic crate handles is critical, as these handles bear the load when the crate is overloaded. If the exhaust in both handles is inadequate, it can result in visible welding seams, making the product more prone to damage.

Also Crate moulds typically utilize 4 or 6 hot runner drop gates, or sometimes a 3-plate design, to accommodate their large size and complex shapes. This configuration is essential for ensuring even material flow and consistent quality during production.

Additionally,

incorporating 4 sliders enhances the mould's functionality, allowing for efficient ejection and facilitating the creation of intricate designs while maintaining structural integrity. This thoughtful design approach ensures that the final product meets both durability and performance standards.

In addtion ,Mold design is also a very important part of crate mould .
