Low Volume Manufacturing Service

Low volume manufacturing is a specialized service offering full production-quality parts but in volumes usually limited to 100,000 pieces or fewer, depending on the process used. This is an increasingly popular option for many product categories, allowing for a more limited investment in tooling and materials while providing quick access to markets, rapid response to shorter product life cycles and as a bridge between initial prototypes and high-volume production.

Injection mold should consider these three processing technologies

In the process of injection mold processing, the complete professional technology is an indispensable project. It involves transforming plastics into products that maintain the performance of the original system. The important production process design conditions of injection molding are the temperature, pressure and corresponding different effects that affect the plasticization flow and cooling. Here, our analysis can be roughly divided into three aspects: first, temperature and control, second, pressure management and control, and third, forming cycle. There are 3 […]

Several cases of mold deformation

Deformation in the processing of molds and parts is a headache, and it can not be completely avoided. Once a mold or part is deformed in the processing process, there will be losses, and safety problems will be caused. How many cases will the parts or molds be deformed?
1. The internal force changes the machining accuracy of the part. In the machining process, the part is locked by the three claws of the lathe, so that the force on […]

Mold manufacturing process

Mold manufacturing refers to the processing of forming and parison tools, as well as shear and die-cutting molds. Generally speaking, the die is composed of upper die and lower die. The steel plate is placed between the upper die and the lower die to form the material under the action of the press. When the press is opened, take out the workpiece or corresponding waste determined by the shape of the die. Process planning steps for precision die processing?
Mold […]

What problems need to be solved in the design and manufacturing of injection mold?

What problems need to be solved in the design and manufacturing of injection mold? let me show you.
1. Reasonable structure selection: select appropriate molding methods and equipment according to the drawings and technical requirements, and give the structural scheme of injection mold in combination with the plant capacity. In the process, it can be comprehensively discussed and studied in combination with the opinions of relevant parties.
2. Dimensional standard of injection mold molding parts: the molded parts are extremely important, […]

How many suggestions did we mention for mold protection?

If there is no effective mold protection, the mold will be damaged. We gives you the following suggestions:
When disassembling the mold, avoid bumping and drenching, and move stably.
Spray hot mold, and then spray a small amount of release agent.
Conduct a comprehensive inspection of the mold and carry out anti rust treatment: carefully wipe out the moisture and sundries in the cavity, core, ejector and row position, and spray anti rust agent and grease on the plastic mold.
The maintenance of […]

Foresight of mold design in Dongguan injection mold factory

As a mold designer of Dongguan injection mold factory, we must have foresight in design: list all possible mold problems, and then make foresight mold products with reference to past design ideas.
The mold designers of Dongguan injection mold factory fully consider the product structure and assembly. At the same time, they also need to consider the product demoulding, waterway layout, gate distribution, etc. the following will briefly introduce the design points of the product’s ribs, buckles, nut holes and […]

How to solve the side wall dent of injection molding products

The “dent” is caused by the local shrinkage after the gate is sealed or caused by the lack of material injection. The depression or micro depression on the surface of injection molded products is an old problem in the process of injection molding.
Dents are generally caused by the increase of the shrinkage rate of plastic products caused by the increase of the wall thickness. They may appear near the external sharp corner or the sudden change of the wall […]

How to choose the best gate location

1. The gate must be designed in the area with the largest wall thickness.
2. The gate should not be set near the high stress area.
3. For the long parts, especially for the reinforced mixture, if the motor is possible, the gate should be set along the longitudinal direction rather than the transverse direction or in the center.
4. If there are two or more cavities, the parts and gate should be symmetrically arranged along the sprue.
5. For axially symmetrical parts, […]

How to solve the problem of insufficient filling in the process of plastic injection molding

In the process of plastic injection molding, there will be a variety of problems, and insufficient filling is a phenomenon with high probability, so what is the reason for insufficient filling? How should we solve this problem? Mr. Fu, a teacher of Jiangsu injection molding factory for many years, shared it with you.
Plastic injection processing
1、 The main reasons for insufficient filling in plastic injection molding are as follows:
1. Insufficient resin capacity.
2. There was insufficient pressure in the cavity.
3. The […]

Analysis of cooling time in injection molding

The cooling time of plastic injection molding products accounts for about 80% of the whole injection molding production cycle. If the injection molding parts are cooled properly, the product quality is qualified. If the cooling is not qualified, it will lead to warpage deformation or surface defects, which will affect the dimensional stability of the products. The injection molding manufacturers analyze the cooling of injection molding parts for you.
The cooling time of injection molded parts generally refers to the […]
