Sometimes a Plastic moldmaker is looking for a good niche products which related their business and they could trust on. Such was the case for SINCERETECH a well-known plastic mold maker that is now inverted molding shop in a 5,000 -sq Class 10,000 injection molding cleanroom.

Located in Dongguan China, a small town in the DongGuan City of China near the Shenzhen airport, SINCERETECH has a reputation for complicated, high-precision molds, automobile mold and a particular specialty in multicomponents molds.  As other tool making companies have done, in 2005 the company started plastic mold making business to make export molds, primarily of shorter runs for customers of its toolmaking business.

Staying with what worked, when SINCERE TECH were set up as a plastic molding facility by a wall divided from the plastic mold making shop, it was designed around what the mold customers were doing. That way it could handle customers’ short lead time, benefits for mold maintaining, and so on. Since molds were mostly made for technical and multi material or colored parts, the molding company configured with high-precision injection molding machines and multicomponent technologies. Molding presses range from 60 to 2000 tons and include two-shot injection molding machines. you can go to our double injection molding parts page.

Medical Products needs molding cleanroom 

Several of our customers were in medical equipment, automotive industrial, health care industry and pharmaceutical manufacturers. to provide a custom solution for all of our customers, ST decided to set up a molding cleanroom manufacturing operation at a Class 10,000 level with turbulent airflow.

The ways of using injection molding machines in a cleanroom environment are too numerous to count. There are hoods over individual machines, machines completely in the cleanroom environment, and machines partially in the molding cleanroom itself.

ST decided to put only the clamp end of the machine in the injection molding cleanroom, “We considered the particular characteristics of the machines in all our planning.” ST chose some of high precision Series injection machines, including 65-, 80-, and 110-ton machines to cover its product range, this machines seems working perfect as we thought at the beginning,

Full-service Plastic mold making, normally molding and Cleanroom 
ST did not set up the molding cleanroom to simply molded parts. That would not have fit with the level of service expected by medical customers. Such customers generally specify medical degree for all of molding equipment, assembly and shipments, to complete this task, ST operates an assembly room within the Class 10,000 cleanroom so that the finished product leaves in hermetically sealed packages ready for shipping.

For normally requirement we have range to machines from 80 tons to 2000 tons to produce wide range of the products for our customers.
