Industries that thrive on its manufacturing process are no strangers to the technique of plastic injection molding. The overall process of manufacturing is aided by the accuracy of plastic injection molding.
It has gone a long way since its first appearance in the production process in the 1800s. Since then, plastic injection molding has developed into new technologies that enable you to produce high-quality products and quick manufacturing of plastic parts.
Exploring new technologies in plastic injection molding will do wonders for your business and for the production of your concept of a product. With these new techniques, the design and function of your plastic parts will be efficient.

New material to promote the development of mold inserts
There is a new material can reduce the mold manufacturer’s investment cost and time. Injection mold tooling The new cobalt-chromium alloy, called MP1, specifically for the Rapid Prototyping (RP) device. A direct metal laser sintering (DMLS) process was developed. The material from the German rapid prototyping equipment and materials suppliers EOS (ElectroOpticalSystems) GmbH company. Now users in North America and the United States through the EOS of China CNMOULDING companies to buy such material.
CNMOULDING is an injection mold Manufacturer development company, this company the first time, the materials used in commercial manufacturing. In the company’s use of the process, the cobalt-chromium alloy has been shown to have high strength, high-temperature performance, and corrosion resistance. CNMOULDING was the China introduction of the first EOS’s EosintM-level rapid prototyping machine company because at that time the company had foreseen DMLS-based rapid prototyping huge market. However, experiments found that when the market still does not have a lot of material to meet their customer’s application requirements.
“There are many projects require rapid prototyping solutions, injection molding plastics but the experimental conditions. Our customers need for materials with better high temperature and corrosion resistance and higher mechanical properties.” CNMOULDING the company’s president Kenny Han said, “even if it took more time and money, stainless steel or other alloys still cannot meet their requirements. ”
In order to address these issues, CNMOULDING has selected the EOS of cobalt-chromium MP1 material.
Kenny Han said that the alloy Rockwell hardness of 30 to 40 between the mold to produce small complex products, these products are now typically used or EDM machining methods to create.
Because the structure of this material layer is very thin, only 20μm. So products can be fully sintered. Morris believed that such materials and metal laser sintering technology to help direct Injection Mold Making manufacturer industry. In order to lower the cost of production of fine-type core and cavity inserts. “At present, there is no reason why a lot of mold manufacturers to adopt the technology. In my opinion, is because many people believe that they only used the old order manufacturing mold core and cavity be considered the best,” Kenny explained.
Mold maker CNMOULDING CEO Kenny than not hesitate to adopt the above techniques. Because Tenbusch found that the company’s EOS direct metal laser sintering rapid prototyping equipment. New customers have even extended to Mexico and South America.
In the injection mold manufacturing process, using typical EDM equipment (EDM) is more popular on welding. And wire cutting in the fast-forming mold is also a gradual increase in the use. This, Kenny explained: “With wire, cutting can help us save time. That is, we use wire cutting to cut out the cavity, while the insert such as the fine components using the DMLS process to process.”
CNMOULDING introduced a high accuracy of this method. But do not need to be a lot of measuring points, while rib muscle can be separated and as vents. It can also be processed using the wire cutting some stainless steel inserts, and place them in the mold. If the material hard enough and long enough lifetime. Processing personnel will not have the details necessary to EDM parts, and as for the usual pre-hardened high-tensile steel nitrided die is the case. The use of wire cutting can be 4 to 5 weeks to complete mold manufacturing, which accelerated the root cause lies in the DMLS equipment EOS EDM equipment replaced.
Co-Cr-MP1 is the EOS family of the company’s new stainless steel 17-4 in a series, it is planned to the market this year is MaragingSteelMS1, this is an 18 martensitic steel 300 (Model: 1.2709), its performance at least equivalent to or even superior to the traditional mold steel, very suitable for fabrication using DMLS mold insert.
Less polished, multi-coated
China CNMOULDING technic. is a leading injection mold to provide polishing and electroplating services. Out of consideration for the customer to reduce costs. The company is now seldom used premium EDM polishing technology, replaced by the introduction of plating technology in the mold surface coatings. CNMOULDING Technic Company President Kenny said: “Now is not required each mold polishing, and coating use is gradually growing. We have adopted in lieu of electroplating polishing EDM live, you can save time and money for customers.”
As we all know, fillers will shorten the life of the injection mold. With the injection molding of the growing amount of filler, filler to the mold caused by corrosion and wear to highlight the growing problem. The increase in coating for molds. Such as Nickson (a nickel-PTFE coating) and Nibore (nickel-boron nitride) is able to play a very good protection. At the same time with the plastic lubricant additive expensive compared to those of coating and very cheap.
