Plastic beer box molds are key tools for manufacturing beer boxes and are crucial for ensuring production efficiency and quality. When making plastic beer box molds, the cooling system is a very important part, and using beryllium bronze as the cooling material at the parting surface can bring many benefits.

beryllium bronze has excellent thermal conductivity, which can quickly and effectively transfer the heat on the surface of the mold to the cooling water, effectively reducing the temperature of the mold, accelerating the production speed and extending the service life of the mold. This efficient cooling method can reduce the deformation and wear of beer box molds during the production process, ensuring the stability and quality of production.

2. beryllium bronze is a wear-resistant material that can effectively prevent wear and damage to the surface of molds, extend the service life of molds, and reduce maintenance costs. Using beryllium bronze as the cooling material at the parting surface can ensure the smoothness and precision of the mold surface, making the production of plastic beer boxes smoother and more efficient.

beryllium bronze also has excellent corrosion resistance, capable of withstanding the corrosion of chemical liquids such as acids and alkalis, ensuring the long-term stable operation of molds. This is particularly important for plastic beer box molds, as they often come into contact with various chemical solutions and liquid raw materials during the production process.

4. using beryllium bronze as the cooling material at the parting surface of plastic beer box molds can enhance production efficiency, ensure product quality, extend the service life of the molds, and reduce maintenance costs.

 

 

 

HDPE is the abbreviation of High Density Polyethylene and it is a very common plastic material. There are many advantages to choosing HDPE material when making beer crate.

First of all, HDPE is a relatively strong and durable plastic. This means that the beer crate, made of HDPE, can withstand long-term use and repeated handling. This is of great significance to beer manufacturers and distributors, as they need to ensure the safety and integrity of the products during transportation.

Secondly, HDPE is a relatively lightweight plastic material. Compared with metal or other heavy materials, the crate made of HDPE are lighter during handling, reducing the labor intensity of workers and helping to improve efficiency and save costs.

In addition, HDPE is an economical material. Compared with some other high-grade plastics, the production cost of HDPE is relatively low, which makes the beer crate made of HDPE moderately priced, making it an economical choice for manufacturers.

In addition, HDPE is a recyclable plastic material. Today, with the continuous improvement of environmental awareness, sustainable development has become the focus of people's attention. Choosing to use recyclable HDPE material to make beer crate can reduce the impact on the environment and meet environmental protection requirements.

 

 

In the production process of plastic beer crate mould, the design and optimization of the exhaust system will directly affect product quality and production efficiency. A good exhaust system can effectively remove air and gas, prevent the formation of defects such as bubbles and short bursts, and ensure the surface finish and strength of the product.

To optimize the exhaust system of the plastic beer crate mould, we can take the following measures:

1. Design a reasonable exhaust channel: During the mould design stage, the product structure and size should be fully considered, and the exhaust channel should be reasonably designed to ensure that air and gas can be smoothly discharged when plastic materials are filled. The exhaust channel should be as short and straight as possible, and avoid dead corners and material accumulation areas to ensure smooth exhaust.

2. Increase the number of exhaust ports: Appropriately increasing the number of exhaust ports on the mould can enhance the exhaust efficiency and prevent air from being trapped in the mold. The exhaust ports should be evenly distributed, covering the entire surface of the mould to prevent the formation of bubbles and short injections in the high-pressure area of the product.

3. Adjust the position of the exhaust port: According to the specific shape and structural features of the product, adjust the position of the exhaust port. Exhaust ports are usually set at the farthest end and the thickest part of the product to ensure that the air can be discharged smoothly.

4. Use exhaust needles or pneumatic exhaust systems: By setting exhaust needles on the surface of the mould or inside the mold cavity and using compressed air or vacuum systems to assist in exhaust, the exhaust efficiency can be improved, and the formation of bubbles and short injections can be avoided.

5. Regularly clean and maintain the exhaust system: Regularly clean and maintain the exhaust system, remove accumulated materials and impurities from the exhaust ports and channels, ensure smooth exhaust, and avoid blockages that may cause poor exhaust.

 

 

Plastic beer crate injection mould need to undergo pre-deformation treatment (also known as reverse compensation design), mainly to counteract the irreversible shrinkage and deformation of plastics caused by material properties, process conditions, etc. during injection molding and cooling, ensuring the dimensional accuracy, structural strength and service life of the final product.​

1. The inherent defects of plastic molding must be compensated

1.1 Material shrinkage characteristics

Plastics (such as HDPE, PP) undergo volume shrinkage when melted and cooled (typical shrinkage rate 1.5% to 4%).

Anisotropic shrinkage: The shrinkage rates in the flow direction and the vertical direction differ significantly (for example, HDPE shrinks by 1.5% in the flow direction and 3% in the vertical direction), resulting in warping deformation.

1.2 Uneven cooling

The differences in cooling rates in different areas of the mold can cause thermal stress concentration. For instance, the edges of the plastic beer crate cool down quickly while the center cools down slowly, resulting in concave or convex deformation.

1.3 Molecular orientation and residual stress

When the melt flows, the molecular chains are arranged along the flow direction. After cooling, internal stress is formed. It may be released after long-term storage or under force, resulting in dimensional changes.

2. The functional requirements of the beer crate drive pre-deformation

2.1 High dimensional accuracy is required

The beer crate need to be precisely coordinated with the filling line and transport pallets. If the dimensional deviation exceeds ±0.5mm, it may lead to problems such as bottle jamming and unstable stacking.

2.2 Load intensity requirement

Each case needs to carry 24 to 36 bottles of beer (with a total weight of 15 to 25 kilograms). If stress concentration occurs due to deformation, it is prone to cracking at weak points.

2.3 Recycling requirements

The plastic beer crate needs to withstand more than 200 times of loading, unloading and cleaning. Pre-deformation treatment can prevent irreversible deformation caused by long-term stress relaxation.
