Manufacturing Equipment
Our Services
Based on the whole life cycle product and project management, Sofine provides "one-stop" end to solution from design conception to perfect fulfillment. this practice makes the cost effective, best quality and delivery value added to our customer.
Sofine have professional PIM team over 10% of total employees, many of them have more than 15 yesrs experences in spare part. We can provide world class design and engineering practice to customer by ways of tooling design, prototyping, and advanced technology R&D lab transferring.
Mold And Design
1,Capability Overview
Before sintering, Sofine utilize a special debinding
technology to remove binder, which is an
environment friendly process and easy to monitor.
Sintering process keeps running under the vacuum
or high temperature. We can precisely control
various alloy by using different gas. Our continual
sintering furnaces can meet customers’ demand in
the aspect of high productivity and efficiency.
2,Processing
We has high-end precise welding molds, accessories and measure manufacturing technology. We promote fabrication speed and accuracy by investing latest equipment and technology.
Here are some processing equipment and competence:
3,Pre- sale technology
Sofine mold technology is leaded by a trained design and engineering team, and this team can make your ideas come true. Our strictly managed engineers are familiar with production, injection molds, fixture and measure instruments. We utilize 3D software, such as ProEngineer and SolidWorks. We offer one stop design services, which includes industry design, FEA, 3D process analysis, mold flow analysis, etc.

How MIM Works
The MIM process combines the design flexibility of plastic injection molding with strength and integrity of wrough metals to offer cost effective solutions for highly complex part geometries.
The MIM process is typically explained as four unique processing steps (Compounding,Molding,Debinding and Sintering) to produce a final part that may or may not need final finishing operations.
1.Feedstock Manufacturing
Sofine has the competence to use dedicated
device for MIM raw materials mix production.
We can accurately mix batch powder and binder
under controlled environment, and then maintain
high quality and flexibility.
2.Molding
We use the most advanced and sophisticated
injection equipment in the market.
We believe that we can realize higher performance
and production quality by using machine debugged
by technicians.
Sofine updates injection equipments and achieve
automation production.
3.Debinding And Sintering
Before sintering, Sofine utilize a special debinding
technology to remove binder, which is an
environment friendly process and easy to monitor.
Sintering process keeps running under the vacuum
or high temperature. We can precisely control
various alloy by using different gas. Our continual
sintering furnaces can meet customers’ demand in
the aspect of high productivity and efficiency.
4. Measurement and laboratory
Sofine has a modern and well-equippedmetering
department. Our acquired superior devices,
like visual inspection system,3D coordinate measuring
machine, scanner and special instruments for arc,
surface roughness, laser particle and metallographic,
etc. Laboratory is responsible for the maintenance
