Japanese injection molding machine supplier Nissei Plastic Industrial says it has delivered more metal injection molding (MIM) machines than any of its Japanese competitors and it sees vast potential for the technology particularly in China where the MIM processing industry is booming in recent years.

The refurbished ARBURG Technology Center (ATC) in Radevormwald is back in operation. After a two-year modernisation phase, on 7 June 2024, ARBURG Partners Juliane and Michael Hehl, together with the Managing Directors and project leads, cut the reopening ribbon. This event, marked by an open house, followed an exclusive event the previous evening. The two-day event was attended by a total of around 250 guests.

Benefit from our expertise and lower the costs for your injection moulding production by optimising your energy requirement.

During the two-year transition period, the ARBURG staff in Radevormwald did everything possible to continue to offer customers the best support, with total dedication and flexibility. The team of thirty plus were based in an office building around a kilometre away. At the temporary location, the office work and customer service hotline were able to continue 100% in house. The good, long-standing relationships with customers proved to be an advantage. For application technology and training, the ARBURG staff was able to use the customers' machines on site.

Automatic clamping force adjustment automatically adjusts clamping force fluctuations caused by rising mold temperature during automatic operation, while direct clamping force setting permits changing of the clamping force setting during automatic operation.

Japanese injection molding machine supplier Nissei Plastic Industrial says it has delivered more metal injection molding (MIM) machines than any of its Japanese competitors and it sees vast potential for the technology particularly in China where the MIM processing industry is booming in recent years.

An exclusive event was held the evening before the opening celebration; the official portion followed on 7 June with Managing Partner Michael Hehl and Managing Director Technology & Engineering Guido Frohnhaus. In total, around 250 invited customers and partners used the opportunity to take in the new facilities. All seven ALLROUNDER machines were in operation, showcasing interesting applications to demonstrate the wide range of injection moulding products and services. The programme of events was rounded off with presentations on hot topics such as digitalisation, sustainability and hybrid machine technology.

Nissei will bring an MIM unit to the 17th DMP China Dongguan International Plastics, Packaging & Rubber Exhibition in Dongguan, China, from November 18th to 21st. The NEX-IIIT Series 784-kN (80-tonne) clamping force electric injection molding machine is manufactured at the company's Taicang factory in China and at the show, it will be molding SIM card holders using SUS630 stainless steel in a four-cavity mold.

The machine features higher injection velocity, response, and pressure achieved by adopting a low inertia servomotor and a customized injection unit. Further, higher injection/plasticization precision and wider moldable range are materialized by optimizing the barrel temperature control. In addition, yield is improved by the high-precision metering control.

Shortly after the 40th anniversary celebrations, the ATC was cleared and gutted in August 2022. The comprehensive renovations and modernisations included installing photovoltaic and geothermal systems, a triple-glazed glass facade and efficient roof insulation. Following the renovation and thanks to the use of renewable energies, the annual primary energy requirement of the ATC Radevormwald is around just 40% of that of a newly built reference building. In addition, the top floor now accommodates redesigned training rooms with state-of-the-art presentation equipment. The technical centre also fulfils the latest requirements.

Nissei's linear pressure toggle system, meanwhile, possesses advantages of a toggle mechanism, particularly fast molding cycles, but it is also designed to possess performance similar to a hydraulic direct clamping machine: automatic clamping force adjustment and direct clamping force setting are featured as standard.

For reliable performance, a slimline design and an unbeatable price, there is only one choice: the new ALLROUNDER 720 E GOLDEN ELECTRIC!

MIM has been used extensively by the mobile phone industry, and its application has also been expanding to the automotive and medical market segments according to Nissei. With its abundant experienced in metal injection molding  MIM ability to explore the use of new materials, Nissei is seeking to tap into new markets while simultaneously receiving repeat orders from existing customers.
