This is a listed company with a history of more than 20 years. It specializes in making sensing technology products. It cooperates with our company in the key plastic parts of automotive sensing electronics and atomizing electronics. The cooperative products involve in mold injection molding of metal parts. The dimensional accuracy and appearance requirements of the products are high, and the injection molding volume of the products is relatively large.

 

Taking a product as an example, the customer's previous mold design is one out of two, each mold hole needs to put two plug-ins, and after the product is out of the mold, only two inserts can be taken out one product by one. Due to the previous low production efficiency, we hope to improve it through cooperation with us.

 

After many internal discussions, we put forward a solution from the source of mold design. The number of holes is changed to one out of four. Only one insert needs to be placed in each mold hole for injection molding. After the product is out of the mold, all the inserts of the four products are removed at one time with a special fixture, which greatly improves the production efficiency and high customer satisfaction.

Helmet mold is one of our best fields in the past 20 years. The companies we cooperate with are well-known helmet factories in the industry at home and abroad. We can realize that customers only give design renderings, and we turn them into 3D drawings with reasonable structure; From half helmets to full helmets, from full helmets to combined helmets, or vice versa.

 

Our experience in helmet mould is cross industry, including motorcycle helmet, automobile helmet, labor protection helmet, engineering helmet, sports helmet and so on.

For more than 20 years, our company has focused on the one-stop production service of mold development and processing in the lens industry. It is the head manufacturer in China's lens manufacturing industry.

 

The case to be mentioned here is an American company with a history of 100 years and one of the 20 most famous enterprises in the world. The product we cooperated with is a respirator mask, which is a product they have been mass-produced. However, from the perspective of quality assurance and cost advantage, the partner finally chose us for product redevelopment.

 

The structure of this product involves air tight assembly; The optical requirements of products should also meet international standards; In addition, the embedding of metal parts should ensure that the tensile force of the product meets the standard and does not break. This is a typical product that requires excellent comprehensive technology to achieve mass production.

 

We conducted a very rigorous demonstration process from mold design to trial assembly of post process, and finally formulated a set of process flow scheme meeting all the needs of customers, which was fully affirmed by customers and reached the strategic direction of long-term cooperation between the two sides.

The partner is a trader, and the molds need to be exported. This product is a building environmental protection project, with new building structures and new building environmental protection materials. The main technical difficulties are as follows:

 

Mold: This product is spliced with each other. It is required that there should be no mold inclination around the product, and full-automatic injection molding should also be realized. The product belongs to deep cavity, which is difficult to process, and the inner shape is complex. Moreover, there must be a cooling system in each mold part. We split the mold core into more than 100 parts, all of which are precision machined by high-speed machine. The inner deep cavity is processed by precision spark machining, and then all parts are spliced without grinding, so that the mold can be produced smoothly, and the production rhythm is within the scope of customer understanding.

 

Injection molding product processing: as this is a new type of plastic, containing wood powder, poor fluidity and relatively complex product structure, temperature control is also particularly important. The control of injection molding temperature plays a key role in the appearance of this product.

 

It took half a year before and after the project, which was successfully exported and received satisfactory feedback from end customers. Every new material project needs to be professional and patient enough to help customers create successful products.

The cooperative company is a listed company dedicated to scientific analytical instruments. Most of the plastics used have anti-corrosion and high temperature resistance requirements, and the application range of special plastics is wide. Customers' products are processed from machining to injection molding, and their product characteristics are difficult in molding effect, especially PFA and FEP materials, The shrinkage rate of products with different wall thickness ranges from 3% to 6%, and the mold temperature will also have a great impact on the product. The size is very difficult to control. The injection temperature of the product reaches about 340 degrees, the mold temperature reaches 220 degrees, and the requirements for the hot runner are relatively high. In addition, product injection molding is very sensitive to internal stress. As long as there is internal stress in the injection molding process, the product will be black and opaque.

 

Our company must formulate a set of process scheme belonging to this customer from the comprehensive consideration of pre judgment in the mold design stage and technical breakthrough of molding. After several years of running in, our professionalism and service have been greatly recognized by customers, and the two sides have become long-term partners.
