As science and technology evolve and people put forward increasingly higher requirements on appearance, comprehensive performance, safety and environment-friendly features of products, silicone rubber, particularly liquid silicone rubber (LSR), by relying on its light transmittance, durability, nontoxicity, harmlessness and wide operating temperature range, has developed rapidly in recent years. So far, silicone rubber has been widely used in all aspects of life including medical treatment, electronics, automobile, and personal care, etc.
On March 18-19, KraussMaffei, a world-leading manufacturer of machinery and systems for the production and processing of plastics and rubber under CNCE, held the activity of “Switch to Sustainability” KraussMaffei LSR Pioneers! Day 2021 at its integrated plant in Jiaxing, officially launched its all-electric injection molding machine in China and demonstrated six types of silicone applications at the site, comprehensively displaying the leading advantages of its customized silicone solutions in meeting the requirements on diversified applications and helping its users improve their performance.
KraussMaffei LSR Pioneers! Day 2021
As a technical service partner of the plastics & rubber industry, KraussMaffei, by relying on its global advantages and innovations, operates uniquely in the field of LSR molding. The all-electric injection molding machine boasts excellent precision, stability, cleanliness and yield rate, etc., uses the leading SilcoSet technology, and is suitable for processing various silicone products.

During the activity, KraussMaffei displayed six types of silicone applications such as pacifier, blood-collecting tube sealing plug, miner’s lamp lens, medical silica gel column, smart household pulley, and sucker. In addition, in some challenging areas, such as optical applications and clean room production, etc., SilcoSet technology also features a series of solutions for LSR with high transmittance. Take Fresnel lens for example, KraussMaffei’s SilcoSet technology can be perfectly used for injection molding of LSR with low viscosity and high transmittance and micro-structure with a size of 3-5 microns. It meets the requirements on clean room and ensures integration between thin-wall application and functionality under the condition of the same amplification factor.
Six types of applications of KraussMaffei all-electric injection molding machine
The injection molding applications of LSR materials always have stringent requirements. KraussMaffei all-electric injection molding machine can provide the silicon rubber processing process with efficient and reliable supports.
1. Classic frame structure design, operation on the precise linear guide, high parallelism, and low energy consumption.
2. High precision and repeatability for position control in the process of spotting ensures a successful vacuum pumping process.
3. The full-closed loop control system monitors and coordinates each movement and increases the stability.
4. Non-contact pull rod design, no need for lubrication, very suitable for the production environment of clean room.
5. The independently-developed and patented APC plus self-adaptive process control compensates for process fluctuation under the precondition of considering material characteristics, and ensures consistent injection weight and a processing process featuring high finished product rate.

“Thanks to the improved features of new materials, silicone is being used in wider and wider areas. As one of the earliest manufacturers for silicone processing, KraussMaffei has accumulated rich practical experience all over the world. The all-electric injection molding machine and its diversified solutions are developed innovatively for the Chinese market. KraussMaffei has set a new standard in terms of precision, stability and efficiency, provided silicone users with more options, and further enhanced its cost effectiveness,” said Mr. Xu Yutang, Vice President of KraussMaffei China for Product Planning.
During the activity, KraussMaffei not only demonstrated the precise, stable and diversified customized solution, but also partnered with Wacker Chemicals, 2KM, Bole and Elkem to share LSR cutting-edge technologies and innovative applications in their respective fields.
In the future, KraussMaffei will cooperate with its partners, further develop new technologies and applications for silicone processing, and provide Chinese and global customers with more technical expertise and value-added services.
Meanwhile, KraussMaffei injection molding R&D and technology center at the integrated plant in Jiaxing will also play an active role. Covering an area of 1,200 square meters, the center integrates functions of test, R&D and training, etc., and boasts a professional team of engineers, which can provide silicone users with supports in terms of module test as well as development and tests of new products, new technologies, and new materials.
