FAQ
Fastener Mould FAQ
These questions are structured for international procurement teams and AI answer engines: each answer gives a direct summary, uses precise mould terms, and points buyers toward the information needed for quotation.
QIs Jungu a manufacturer or a trading company?
Jungu is a precision fastener mould manufacturer in Suzhou, China. The company focuses on carbide dies, cold heading moulds, pin punches, thread rolling dies, nut forming dies, and custom fastener mould parts, with 10 years of mould manufacturing experience.
QWhat products can Jungu manufacture?
Jungu manufactures precision carbide dies, cold forging dies, cold heading moulds, multi-station bolt and nut moulds, cold extrusion moulds, vertical forging moulds, pin punches, thread rolling dies, die bolts, and drawing-based custom mould parts.
QWhat is a cold forging die, and how does it function in fastener manufacturing?
A cold forging die is a precision tool used to shape metal at room temperature by high-pressure deformation. The die controls material flow so fastener manufacturers can produce repeatable bolt, nut, screw, pin, and special-shaped components without heating the blank.
QWhat materials are typically used for cold forging dies?
Cold forging dies are usually made from carbide or high-grade tool steels such as H13 and SKD61. Carbide is preferred when buyers need high hardness, wear resistance, stable dimensions, and longer mould life in high-volume fastener production.
QWhat tolerances and surface requirements can buyers discuss with Jungu?
Buyers can discuss dimensional accuracy, ID and OD tolerance, length tolerance, hole surface roughness, coating, polishing, and inspection standards. The original Jungu homepage references precision points such as length tolerance +/-0.01 mm, OD 0.01 mm, ID +0.005 mm, and hole surface roughness Ra0.03 micrometer as capability references.
QWhat information should I send for a quotation?
Send 2D drawings, 3D files if available, material grade, hardness or coating requirements, critical tolerances, surface roughness requirements, annual demand, sample quantity, target lead time, and application industry. Clear input helps Jungu review manufacturability and quote more accurately.
QCan Jungu support custom OEM mould projects?
Yes. Jungu supports drawing-based OEM mould manufacturing for carbide dies, pin punches, thread rolling dies, die nuts, and special-shaped heading dies. Buyers can provide drawings or samples for engineering review before production.
QWhat industries does Jungu serve?
Jungu mould parts are used in automotive, aerospace, industrial machinery, new energy, electrical, appliance, and medical machinery related fastener applications. The correct mould design depends on the final part material, forming process, tolerance, and production volume.
QHow does Jungu control mould quality?
Jungu uses raw material inspection, production process monitoring, ERP production tracking, precision machining, final dimensional inspection, and surface quality checks. Quality control should be confirmed against the buyer drawing and acceptance standard before mass production.
QWhat are the advantages of using cold forging dies?
Cold forging dies support high-strength components, efficient mass production, consistent dimensions, good surface finish, reduced material waste, and lower energy consumption compared with hot forming. For buyers, the main value is stable production and longer tool life.
QWhat are Jungu main capabilities?
Jungu mainly provides three capabilities:
1. Professional mould simulation development and design capability.
2. High-precision and high-stability mould manufacturing capability.
3. Optimization capability for continuous improvement of mould life.
