DFM Report

A comprehensive DFM report for a mold making project will be the first step to success. In order to reduce the risk in the manufacturing process, as a mold manufacturer, we try our best to inform customers of potential problems in advance.

Mold Flow Analysis

Our mold flow analysis works to pinpoint issues that can arise from these difficult flowing materials as well as other issues like thin walls and complicated geometries, providing solutions to improve flow and mold ability.

Mold Tooling Production

According to your special application needs, using the materials and surface treatments you requested, start the production of mold.

T1 mold trial

The more potential defects that are identified and corrected in the T1 sample, the fewer additional sample runs will be required during the development of the finished product. Correctly identifying defects at this stage can save you a lot of time and money.

Low volume production

After completing the trial production phase, we proceed to low volume production to check the quality of products again and send samples for test and previous promotion.

Strict Inspection

A strict inspection process includes the inspection of function, dimension, appearance and can pass all industry requested test in actual application, ensures that the parts meet the required specifications and are of high quality.


After a complete inspection, we will deliver your products or mold to you as quickly as possible while ensuring their safety.
