Chipboard Screw Carbide Die Manufacturing Process

In modern industrial manufacturing, The thread chipboard screw is an essential fastener widely used in woodworking and construction applications. Screws are fundamental fasteners, and their production quality directly impacts the reliability and safety of the end products. She quality of screws largely depends on the quality of the production dies.

Classification and Function of Chipboard Screw Carbide Dies

Chipboard screw carbide dies are primarily divided into two categories: header dies and thread rolling plates. The header die is responsible for forming the head structure of the screw, including core components such as the main die, wire die, scissors, upper punch, lower punch, punch sleeve, and sleeve piece. The thread rolling plate is mainly used for threading and is divided into two types: machine thread rolling plates and self-tapping thread rolling plates. The perfect match of these two types of dies ensures the precise forming of screws.

Key Material Selection

Chipboard screw carbide dies typically use high-quality hard alloy materials, such as tungsten carbide (WC-Co). These materials offer excellent wear resistance, high hardness, and good toughness, meeting the long-term use requirements of screw dies. Depending on different application scenarios, the cobalt content in tungsten carbide is generally adjusted between 6% and 15%. The choice of die material directly determines the product’s service life and processing quality. The core components of header dies use high-quality tungsten carbide, significantly enhancing the die’s lifespan. In contrast, thread rolling plates need to meet multiple performance requirements: extremely high hardness ensures processing accuracy, excellent wear resistance extends service life, sufficient strength and impact resistance ensure processing stability, and outstanding fatigue resistance ensures long-lasting durability.

Refined Process Flow

The manufacturing of chipboard screw carbide dies follows a strict process flow: starting with preheating, followed by precisely controlled heating treatment, then professional cooling and cleaning processes. The subsequent tempering process is crucial for ensuring die performance, requiring precise temperature and time control. Grinding: precision grinding with a diamond wheel. Polishing: to improve the surface finish of the die. Thread processing: precise threading using specialized CNC equipment.

Strict Quality Control

Dimensional inspection: precision measurement using a coordinate measuring machine.

Hardness testing: to ensure the required hardness value is met (typically HRA88-92).

Surface roughness testing: to ensure it meets design requirements
