Puller Guide Pin
Product Introduction: High-Quality Puller Guide Pins / Threaded Guide Pins
In injection molds, die-casting molds, and large mold structures, Puller Guide Pins are critical components that combine guiding and load-bearing functions. They not only provide guidance between the moving and fixed mold halves but also feature threaded holes for connecting lifting eye bolts, facilitating mold lifting and transportation. As a mold manufacturer that produces for our own use, we maintain extremely stringent standards for concentricity, thread strength, and wear resistance of puller guide pins. Every pin undergoes precision machining and rigorous inspection to ensure precise guidance, reliable load-bearing, and safe lifting during long-term high-frequency operation.
Self-Produced and Self-Used, Rigorously Selected
We are not only a supplier of mold components but also a mold producer ourselves. Through extensive practical experience in our own molds, we have repeatedly validated the steel selection, heat treatment process, thread strength, and surface wear resistance of puller guide pins. Only those with good concentricity, sufficient rigidity, and exceptional durability are approved for our supply system.
Premium Materials, Strong and Wear-Resistant
Our puller guide pins are manufactured from SUJ2 bearing steel or SKD61 hot work mold steel, undergoing carburizing and hardening or through hardening treatment to achieve a surface hardness of HRC58-62 while maintaining good core toughness. Excellent wear resistance and bending strength ensure dimensional stability and precise guidance during long-term high-frequency operation.
Precision Grinding, Concentricity Guaranteed
The outer diameter of each guide pin is precision ground using high-precision centerless grinders, achieving roundness within 0.005mm and surface roughness below Ra0.2μm. The guiding section that mates with the guide bush is precision ground to ensure smooth, stick-free movement, effectively protecting cores and cavities from lateral forces.
Threaded Design, Multi-Purpose Function
The pin head features a standard threaded hole (metric or imperial) for direct installation of lifting eye bolts, facilitating mold lifting, transportation, and maintenance. The internal thread features a high-strength structure with special strengthening treatment, offering strong load capacity and ensuring safe lifting. Thread specifications cover M8 to M30 and various standards, adapting to different lifting eye bolt sizes.
Multiple Structures, Strong Adaptability
We offer various structural types of puller guide pins to meet different mold requirements:
Standard Puller Guide Pin: Head with internal thread, tail with mounting step, suitable for conventional molds
Extended Puller Guide Pin: Extended guiding section, suitable for long-stroke molds or special opening distance requirements
With Oil Groove Type: Spiral oil grooves on guiding surface for lubricant retention, reducing friction and wear
Two-Piece Puller Guide Pin: Segmented design for easier processing and replacement, reducing operating costs
Anti-Rotation Type: With positioning flat or keyway to prevent pin rotation, suitable for precision guiding applications
Easy Installation, Simple Maintenance
The pin tail features a standard step design for tight fit with the mounting hole in the mold plate, ensuring perpendicularity and positional accuracy after installation. The head internal thread facilitates lifting eye bolt connection without requiring additional lifting holes. The modular design allows for easy disassembly and maintenance. In case of wear, individual guide pins or bushes can be replaced separately.
Complete Specifications, Customized Solutions
For standard specifications, we maintain regular inventory of common diameters (16mm to 60mm), lengths, and thread sizes for quick dispatch. For non-standard customization, based on your mold structure and load requirements, we offer custom puller guide pins with special diameters, special lengths, special thread specifications, and oil groove or anti-rotation features.
