This foldable banana crate is so useful that we have already made 2 sets injection molds for our customer, and now we are making the third sets. Our customer is the biggest banana supplier in Mexico, and they would like to transport bananas from Mexico to USA. In the beginning, they asked us to design one crate which can be stacked up for 8 crates in each row without any deformation of crate. It means the crate should be strong enough as each crate has more than 15 kilos of banana inside, and the bottom crate must bear at least 105 kilos. Besides, when the crates are sent to the ripening room by forklift, they cannot be shaken or fallen, although they are stacked eight stories high. It means our design should be very precise to avoid any shaking or falling between the crate and the crate during handling.

The characteristic of this kind of multi-color injection moulding is to transform the general single color product into a multi-color mixed product without changing the mould, making them like various grain patterns such as wood grain, marble, jadeite and so on, without having to go through two processing procedures such as spray painting and water dyeing.

Design and manufacturing of handle mould--- 1. Mold design of handle mold with 4 ~ 32 cavities. 2. Steel of mold cores and cavities is stainless steel with heat treatment. 3. Design of interchangeable die components for easy maintenance. 4. Specially designed nozzle and fast color changing hot runner system according to customer’s requirement. 5. All molds parts are machinery with CNC equipment.

Spray cap molds are used in the molds for producing insecticide shells. They are made in accordance with the shape of the insecticide cover required. They are injection molded with plastic and processed into insecticide shell parts through various processes. The principle of the spray tank is that the liquid is pressed out of the valve by using air pressure. The liquid can be sprayed evenly. The direction and dose can be controlled. Any content can be easily put in and easy to use.

Thin-walled container molds must have high-end polish, as most the fast-food boxes are transparent. That is why we used H13 as the steel material for this thin-walled ice cream box. H13 steel is the most widely used and representative hot work die steel. Its main characteristics are: 1. It has high harden ability and high toughness. 2. Excellent thermal crack resistance, which can be water cooled in the workplace. 3. With medium wear resistance, carbonizing or Nitrogen processes can also be used to increase its surface hardness, but the thermal crack resistance should be slightly reduced. 4. Due to its low carbon content, the secondary hardening ability is poor in tempering. 5. It has anti-softening ability at higher temperatures, but the hardness will decrease rapidly when the use temperature is higher than 540 ° C (1000 ° F) (that is, the working temperature can be 540 ° C). 6. Small deformation during heat treatment. 7. Medium and high machinability. 8. Medium decarburization resistance.

The two-color mold technology uses multiple materials for injection molding production, and combines the characteristics of different materials during the molding process to assemble or other suitable bonding methods to improve product functionality and aesthetics. Automotive lights in two-color molds are an important application area. The features of double color car lights molds are as below: 1. The moving side of double color molds will be rotated by rotary table of double color injection machine. Hence, car lights shall be fixed on moving mold well to avoid being stuck in cavity side. 2. The fixing position after mold rotation shall be very precise, hence, the rotary table of injection machine shall be driven with servo motor instead of hydraulic motor. 3. Injecting stroke shall be designed as shorter as possible in order to enhance the strength of ejecting rod.

This straw handle cup is divided into two sets of molds, one is the cup body and the other is the cup cover. In design, the cup body cavity 2 spring block slides. When opening the mold, it depends on the pull hook on the mold core side to start in an instant, and then the spring pushes the spring block out, and the mold core side directly relies on the machine to push the ejector plate to eject the product and drop. When the cup cover is opened, slide the 2 sliding blocks on one side of the core to both sides through the inclined guide post to separate the sliding blocks from the product. The 2 sliding blocks are designed on the pusher plate to eject the product as a whole.

Mold Structure design advantage: 1. Conventional ordinary mold, no structure, high durability of the mold 2. 4-point hot runner gate to have better balance of the flow channels to consider the balance of the gates, and make the molten materials uniformly charge at the same time. 3. Significantly prolong mold life and shorten cycle time 4. Durable mold steel with P-20H or 718H 5. High efficiency cooling design 6. Ensure mold thickness uniform, equipped with wear plates which sharply increase mold stability and mold life!

Paint bucket mould and plastic moulding painting bucket. The technical point for the painting bucket is the painting bucket wall eccentric and ejection system. Paint bucket is different as all the other kinds of bucket, there is one undercut on the edge of the bucket mouth, and this undercut (rib) need to be stripped before it drop down.
