Plastic Thermoforming

In order to address these issues, CNMOULDING has selected EOS of cobalt-chromium MP1 material. Kenny Han said that the alloy Rockwell hardness of 30 to 40 between the mold to produce a small complex products, these products are now typically used or EDM machining method 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.

Clear Conservative

Mold maker CNMOULDING CEO Kenny  not hesitate to adopt the above techniques. Because Kenny Han 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 a typical EDM equipment (EDM) is a 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 DMLS process to process.”

Kenny  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. 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 life time, 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 a 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 Co., Ltd. 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. Bales Mold Service Company President SteveBales, 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 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 mold, such as Nicklon (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.

The use of submerged gate gate insert to eliminate the visible signs of

This submerged gate inserts from Germany, i-mold company, its injection site was designed in the end products, while the flow channel from the front open, so that the surface of positioning products on the gate inconspicuous place. For example, in product outer edge of the side gate at the bottom of rib muscle, people can not see the obvious signs of the gate.

Automotive Plastic Mould

As we kown, the auto business develop very quickly in past ten year,more and more newest go to the market, lots of automovtive components are made from plastic,that means it need large amount of molds made.

CNMOULDING Co., Ltd is specialized in various types of auto bumpers moulds and it’s auxiliary parts such as grilles. CNMOULDING produce  bumper molds for international automotive OEM brands and doing well in bumper molding. One of the particular features of CNMOULDING is short development time ,it will help our customer launch the product in the market.

we are the company special in automotive parts molding.

As a new material for auto parts, plastic parts can reduce the weight of cars and is energy saving, thus are widely used in auto industry. Plastic material gives auto manufacturer more flexibility in car design, i.e.: inner decoration spare parts, panels, door trims, ABS breaking system, bumpers, triangle, spoiler, etc. Our company has certified by ISO9001, along with professional design team, high performance equipment, we have been cooperative partner of many car manufacturers both china and overseas. our company are capable of providing integral design, structural design, auto mold development, product injection, including panel, door trims, air condition, and bumper analysis for Automotive Parts Molding.

Product design and mold flow analysis

In the process of product design, mold flow analysis software is used to work out best point of the flow. At the same time, to minimize cooling effect, cycle time, warping problems of the product, thus avoiding deformation, welding mark, shrinkage problem. Every important assembling part will be check by jigs and gauges to make sure that all products fit well in its set.

Auto mold processing technology

Measuring is of high importance in auto molds, which affects the assembling and fitting effects of all auto parts. The five-axis nc machine can speed up the feed process, shorten manufacturing cycle, optimize tooling system and simplifying processing cycle time and guarantees the precision of the auto mold.

Auto parts injection technology

In the process of injection, material property, clamping tonnage, injection pressure and cooling system should be taken into serious consideration. Auxiliary equipment as water chiller, mold temperature controller machine should be used when necessary, thus to shorten the cooling time and to improve productivity. Spare parts should be put carefully into specially appliance in order to preserve it well.

Auto parts Mould specific processing:

1.As per sample or 3D drawing design the mould.

2.Purchasing the steel.

3.CNC machining,Drill,Heat treatment

4.High speed CNC machine

5.Assembling and fitting

6.Mirror polish

7.The first mould test
