A Real Factory Focused on Drill Point Screw Dies

Based in Dongguan, Zhonglianda started with one man's trade: our founder, Mr. Liu, and drill point screw dies. The main business has not changed since — we make and deliver our own dies, and we're not a trader or middleman.

Production and Quality Control

From raw material to pre-shipment inspection, every step centers on dimensional stability and in-service die performance.

  1. Step 01

    Raw material

    We select high-speed steel or tungsten carbide based on your screw material, production volume, and die-life requirement.

  2. Step 02

    Cutting, blanking, and EDM

    After cutting and blanking, the material goes through electrical discharge machining (EDM) to form the die's key structures.

  3. Step 03

    Grinding and polishing

    Grinding and polishing improve dimensional stability, surface quality, and in-service die performance.

  4. Step 04

    Inspection

    Before packing, we check key dimensions, drill-point geometry, and surface condition.

  5. Step 05

    On-demand trial-run validation

    When needed, we can arrange a trial run to confirm drilling performance and sample results.
