Small parts, big CO2 savings

The company name says it all. Yixin Precision specializes in precision parts – with two business divisions: Mold making and injection molding production. “We are a full-service provider and often also a development partner for our customers,” says Hon Ping Siow, Director of Yixin Precision. Customers come from the medical technology sector, among others, for which Yixin Precision operates its own class 100K cleanroom.

As part of a customer project, the decision was made to invest in a MicroPower injection molding machine for high-precision micro injection molding. “WITTMANN's expertise and advanced solutions as well as its good references in the field of micro injection molding were a perfect match for our requirements,” emphasizes Siow. "In addition, we had already had good experience with WITTMANN with temperature control units and robots. The WITTMANN products are important building blocks for us to ensure the required high precision, repeatability and efficiency."

In addition to medical parts, optical components are also produced using the new MicroPower machine. “In both areas, there are no compromises when it comes to dimensional accuracy and repeatability,” says Siow. In addition, Yixin has to make sure to precisely adjust the surface quality, which is often decisive for the functionality of the subsequent end product.

On a small footprint

Part weights of three grams and significantly less are standard for Yixin Precision, and customer requirements continue to increase. Components and tolerances are getting smaller and smaller, and geometries are becoming more complex. “This is where WITTMANN's technologies help us to become better and better and thus strengthen our competitiveness,” says Marco Koh, Business Development Manager with Yixin Precision.

In addition to its high precision in the field of micro injection molding, the MicroPower injection molding machine impresses with its very compact design. The machine concept combines a rotary table, auxiliaries, automation, temperature control unit, quality assurance and other process units on a footprint of just two square meters. Flexibility is another major strength of the MicroPower – including the integration of a laminar flow box if the machine is not already being operated in a cleanroom.

Energy efficiency included

Yixin Precision also emphasizes the low energy consumption of the MicroPower. "The machine helps us to reduce our CO2 footprint. Sustainability is a key priority for us," says Wee Lian Teo, Director von Yixin Precision. The company has taken concrete measures to achieve carbon-neutral production by 2030. Customers expect this and it is a matter close to the heart of Yixin's management to actively contribute to climate protection. For example, investments are only made in energy-efficient technology and all processes are optimized, for example through waste reduction initiatives. In order nevertheless to maintain its strict quality requirements, Yixin Precision is taking advantage of the new opportunities offered by digitalization and AI.

WITTMANN also plays an important role in optimizing existing processes at Yixin Precision. One first all-electric EcoPower injection molding machines will soon be put into operation.

“WITTMANN is a very good partner for us,” emphasizes Hon Ping Siow. “Together, we are expanding the spectrum of what is possible for our customers.”
