Hiticha-DAC Die Casting Core Inserts with ±0.005mm Tolerance and 48-52 HRC Hardness for Precision Molding

For die casting mold parts, we use imported steel, such as 1.2344, 8407, DAC, which has good yield and tensile properties, excellent wear resistance, corrosion resistance and impact resistance. Our unique surface treatment technology significantly extends product life. We utilize world-class testing equipment to ensure strict quality control.

Customization cavity inserts are the key forming components in die-casting molds and represent the most demanding parts. Inserts directly affect the entire mold's lifespan. Common failure forms include cracking, erosion, sticking, and deformation, all of which can be effectively improved through advanced manufacturing processes.

We place special emphasis on material selection and insert durability. Years of machining experience, high-quality imported materials, advanced imported machining equipment, leading testing equipment, and a comprehensive quality management system ensure high-quality product components.

Our strength lies in cooling processing capabilities. We operate more than 3 gun drills in our facility and produce over 1,000 cooling core pins monthly. Every item is certified to ensure quality and concentricity within 0.2mm T.I.R. We utilize gun drill machines that exclusively use SR-drills and maintain specialized grinding equipment for gun drill maintenance, which is essential for accurate regrinding. Currently, we can produce Ø3×L=600mm holes with excellent finish and concentricity using SR-drill technology.

Our product range includes: auto die-casting mold core pins and inserts, plastic mold core pins and inserts, movable core components, and more. These are widely used across medical, cosmetics, automotive die-casting, daily packaging, electronic appliances, automation, and various other industries.
