CNC Machining 1.2344 Core Insert Parts with 48-50HRC Hardness for Precision Mold Applications
Core insert parts are manufactured using imported materials, offering excellent anti-rust properties and superior polishing performance. We currently produce 96-cavity mold parts for hot/cold runner bottle preform molds. Our products are machined using imported CNC, OD grinders, and ID grinders to ensure consistent altitude, uniformity, and interchangeability. For specialized applications, we provide surface treatments including TIN and DLC coatings to enhance wear resistance and extend service life.
