Injection molding is to mold molten plastic into a closed mold with a lower temperature through a nozzle under high pressure. Both thermoplastics and thermosetting plastics can be injection molded. In the production of packaging containers, it can mainly produce various box-type packaging containers, such as various turnover boxes and small boxes. For box-type packaging containers, the following aspects should be considered in structural design.
Wall thickness of container
The design of wall thickness mainly considers three aspects: one is thickness; the other is uniformity; the third is smooth transition.
Thickness: The wall thickness of the container is mainly determined by its use, type of plastic, structure, etc. For thermoplastics, it should not be less than 0.6mm, usually 2 ~ 4mm. For thermosetting plastics, because of its poor fluidity, the thickness should be larger, 1.6 ~ 2.5ram for small parts and 3.2 for large parts 8mm, the maximum does not exceed 10mm.
Uniformity: The uniformity of the wall thickness has a great influence on the quality of the container. If the thickness difference of a container is too large, it will cause uneven shrinkage and cause defects such as deformation and cracks. Therefore, the structure should be designed with equal thickness as much as possible.
Gently transition: In some containers, some parts must have different thicknesses due to structural requirements, such as the corners of the container. At this time, a gentle transition should be used to avoid sudden cross-sections.
2. Increase stiffness
Plastic is relatively flexible, and the rigidity of the container made is poor, and the turnover box container sometimes has a large load capacity. Therefore, various structural measures should be taken to improve the rigidity.

What should be paid attention to in the development of plastic bucket molds?
How to solve the eccentricity problem of the plastic barrel mold is the first thing. In this way, the barrel cannot be produced for a long time, and there is no way to repair it in the later stage.
The second problem is the cycle of mold production cycle. Generally, the cycle of 20L barrels in the market is about 40s. If you want to increase the benefits, reduce the cycle time, save labor costs, electricity costs, and time costs.
Conventional customers usually choose steel P20 or 718H. High-end customers will choose 2738, S136 plus beryllium copper. If customers use regrind production, we recommend to do electroplating, which can save the time without frequent lighting.

Plastic Car Door Handle Injection Mould
Product Description
Injection moulding is a manufacturing process for producing parts by injecting material into a mould. Injection moulding can be performed with a host of materials, including metals, (for which the process is called diecasting), glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.

Auto parts car front bumper mold plastic injection mold
A car bumper is a safety device that absorbs and mitigates external impact and protects the front and rear of the vehicle body. Generally consists of plastic bumpers, cushioning materials and beams. Plastic bumpers have strength, rigidity, and decorativeness. From a safety point of view, a car can play a cushioning role in the event of a collision and protect the front and rear body. From the appearance, it can be naturally combined with the car body to form a natural One body, with good decoration, has become an important part to decorate the appearance of the car.
1: Determination of bumper shell material
Regulatory requirements: The front and rear protection devices of the car must ensure that the vehicle will not cause serious damage to the vehicle when a light collision of 4km / h occurs. In addition, the front and rear bumpers not only protect the vehicle and reduce vehicle damage, but also protect pedestrians and reduce the injuries to pedestrians in the event of a collision. Therefore, the shell material of the bumper should have the following characteristics:
1) With less surface hardness, it can reduce pedestrian injuries;
2) Good elasticity and strong resistance to plastic deformation;
3) Good vibration damping effect, can absorb more energy in the elastic range;
4) Resistant to humidity and dirt;
5) Has good acid and alkali resistance and thermal stability.
Modern car bumper shells are mostly made of plastic or fiberglass. In order to reduce the cost of trial production, save mold production costs, and also shorten the trial production cycle, in the concept car trial production, consider using FRP glass fiber reinforced epoxy hand lay-up process.
The materials of the bumper are generally PP + EPEM + T20 or PP + EPDM + T15. EPDM + EPP is also more versatile. ABS uses less and is more expensive than PP. The thickness of the bumper is usually 2.5-3.5mm, and the gas-assisted molding can be made thinner.
Note that if the bottom mesh of the bumper is integrated with the bumper, the thickness of the mesh must be more than 2.0mm, and the die angle should be increased as much as possible (2 degrees or more). If the mesh is separate, the mesh wall of 1-1.5mm is sufficient.

The existing plastic flip cover with an anti-opening protection structure is generally made of polypropylene to ensure the folding performance of the flip hinge. Limited to polypropylene, it has good toughness and can withstand a certain degree of deformation without being damaged. Therefore, most polypropylene anti-opening protection devices can withstand a certain deformation, and the anti-opening protection function is weak, and some consumers can Open the cover when the anti-opening protection structure is destroyed.
