"Production-Ready Trial Run," Professional Strength Wins Trust

It is noteworthy that the super-large die-casting die delivered this time by Borun Mould once again demonstrated the outstanding performance of being "production-ready upon trial run." This achievement not only highlights Borun Mould's core strength in R&D and die manufacturing but also reflects the company's rigorous attitude of "pursuing perfection and going all out" for every single die. From precise planning in die design to meticulous control throughout the manufacturing process, every step embodies the wisdom and dedication of the Borun Mould team, ensuring the quality and performance of the die.

Concurrent with this successful delivery, Borun Mould, has once again won the trust and favor of this client, successfully securing an order for an extremely challenging super-large magnesium alloy die set. This super-large die set can be applied to both magnesium alloy high-pressure die-casting and semi-solid magnesium alloy injection molding. Previously, the technical development and product manufacturing of such super-large dies were considered a blank in the industry. For Borun Mould, this is undoubtedly a brand-new challenge. However, driven by a sense of mission and corporate responsibility, the company is actively engaging in the exploration and development of this new field, contributing to the advancement of the industry.
