Henghui selects optimal carbide materials combined with advanced manufacturing technology to achieve superior die lifespan. Our tungsten carbide straight hole dies feature exceptional wear resistance, excellent polishing performance, low friction coefficient, and very high compressive strength.

While steel molds remain in use due to lower initial cost, tungsten carbide dies offer significant performance benefits that justify the investment. The primary advantage is superior strength - carbide dies provide more satisfactory performance than steel counterparts and last significantly longer, even in extreme operating conditions. This enhanced durability reduces replacement frequency, lowering overall maintenance costs and minimizing machine downtime.
