Precision Mould Products
Focused product families for bolt and screw forming dies, nut forming dies, segmented dies, header punches, thread rolling dies, and cold heading machine tooling. The catalog is organized by the buyer's forming process. Carbide, HSS, coatings, and other materials are reviewed as specifications rather than separate product categories.
Product FamilyBolt & Screw Forming DiesCold heading dies, die cases, and special-shaped forming dies for bolt and screw production.
Product FamilyNut Forming DiesNut forming dies and die sets for multi-station cold forging and stable hole forming.
Product FamilySegmented DiesSegmented die assemblies for complex bolt, screw, and nut cold forming applications.
Product FamilyHeader Punches & Punch PinsHeader punches, recess punch pins, punch cases, and special-shaped punch tooling manufactured from drawings.
Product FamilyThread Rolling DiesFlat and cylindrical thread rolling dies for stable thread profile, surface finish, and long tool life.
Product FamilyCold Heading Machine Tooling & PartsCut-off knives, straightening rolls, transfer fingers, and support parts for fastener cold heading machines.
Focused product catalog for custom tooling
Jungu is not a stock e-commerce catalog. Most projects are reviewed by drawing, material, machine type, tolerance, expected mould life, and current production issue.
