First of all, dairy crate have good stacking capacity and stability. This means that space can be saved during transportation and storage, as they can be easily stacked together. In addition, dairy crate is reasonably designed to maintain its shape and integrity during transportation, thus ensuring the integrity and safety of products.

Secondly, dairy crate is light and easy to handle. Compared with boxes made of other materials, dairy crates are relatively light, so they are easy to carry and move into trucks. This also reduces labor losses and provides customers with more convenient choices.

In addition, dairy crate has excellent thermal insulation performance. This is very important, especially for perishable foods such as milk, which need to be kept within the specified temperature range during transportation and storage. Flat noodles can maintain a certain temperature stability and insulation to ensure the quality and freshness of the product, which is unmatched by other types of containers.

Finally, dairy crate is a choice with good environmental sustainability. Dairy crate can be reused for many times, and can be recycled and reused at the same time. This reduces waste and resource wastage, helps protect the environment, and enhances social responsibility.

In a word, it is a wise choice to use dairy crate, especially for food that needs to be transported and easy to deteriorate, such as milk and other dairy products. Dairy crate has many advantages, including stacking capacity, stability, portability, thermal insulation and environmental sustainability, making it one of the best choices for food transportation.

 

 

 

 

Plastic dairy crate is a commonly used logistics container, and molds are important tools for manufacturing turnover boxes. The hot runner system is an important part of plastic turnover box molds, which can affect product quality and production efficiency. Therefore, a well-designed hot runner system is crucial for reducing costs and improving production efficiency.

The following points need to be considered when designing a hot runner system:

1. Material selection: The hot runner system needs to be resistant to high temperatures, corrosion, and not easily deformed. Usually, materials such as stainless steel or high hardness alloys are used.

2. Layout of hot runner system: The layout of hot runner system needs to consider factors such as product size, model, production efficiency, etc. Normally, it is necessary to design a hot runner based on the product's appearance to make it as short as possible, reduce heat loss, and improve injection molding speed.

3. Hot runner system size: The size of the hot runner system should be designed according to the structure of the mold and the specifications of the injection molding machine. Under normal circumstances, the size of the hot runner should not be too small, otherwise it will affect the flow of plastic, while being too large will increase production costs and also increase the loss of heat energy.

4. Electromagnetic heating: Electromagnetic heating is a modern heating method that can improve production efficiency and ensure product quality. The advantages of electromagnetic heating are fast heating speed, uniform temperature, energy saving and environmental protection.

 

 

1.Purchasing of mould steel

Once the customer has confirmed the mold design, we can proceed with the purchase and cutting of the mold steel. The steel plate is cut by the steel supplier. We simply send the steel purchase order to the supplier. The detailed dimensions of the steel and the detailed tooling requirements are marked on the purchase order. Steel cutting is the first step in mold processing. Steel cutting is done at the steel supplier's factory. Before the steel plate is sent to our factory, we check the hardness of the steel. Checking the hardness of steel can check the quality of steel. Because each different steel has its own hardness level. If the hardness can match the ordered steel, it means that the steel is exactly the same as the steel you ordered.

2.Rough processing

For home appliance molds, the main roughing machine is a CNC milling machine. But for some large parts of the mold, use the mold center to process the mold. Because the machine tool has a large mold and is much faster. After roughing, the mold will continue to use precision machining, including cnc high-speed milling and cnc engraving.

3. Precision processing

Precision processing include CNC engraving tools, high-speed CNC milling tools, electric discharge machining tools, EDW tools and so on.

CNC engraving tools include high speed, medium speed and ordinary speed. Mold accuracy High speed > Medium speed > Normal speed. Therefore, when the parts need high precision, it means that the tool needs a high-speed CNC engraving tool. At the same time, the mold cost high speed > medium speed > normal speed. Therefore, the higher the dimensional tolerance requirements of the parts, the higher the mold cost.

Some dimensions, such as ribs, are very small and narrow in size and cannot be processed directly with CNC engraving tools. In this case, we need to make electrodes and molds by EDM. Electrode materials mainly include carbon and copper. Copper electrodes cost more than carbon ones. Copper electrodes have the advantage of longer life and are not easy to break. Therefore, some very small size EDM tools will use copper electrodes.

4. Deep hole drilling tool

Typically, the cooling line and ejector hole are machined with a deep hole drilling tool. As a normal drill press tool, the hole may not be straight. Therefore, in particular, the ejector hole is not allowed to be processed with an ordinary drilling machine.

5. Injection mold polishing

The die can be assembled and polished after the precise die machining and cooling lines and ejector rod holes are ready. Some household appliance molds need high gloss treatment on the surface of the parts, and the polishing of the molds is very demanding. Therefore, this mold can not be polished by polishing machine, need to be polished by hand.
