Hardware mold accessories
Brief Introduction to Hardware Mold Accessories
As a professional mechanical parts processor with over 15 years of experience,we special ize in manufacturing highquality hardware mold accessories-the corecomponents that ensure precision, durability, and efficiency in mold systems acrossindustries. Our products comply with global standards (IS0 9001:2015, IATF 16949:2016, 1S0 13485:2016) and integrate seamlessly with progressive stamping molds,injectionmolds, die-casting molds, blow molds, and compression molds.
Core Product Categories
Our hardware mold accessories cover five key functional groups, allengineered with industryspecific precision:
Guide Components
Ensure stable aligmment between mold halves dur ing opening/clos ing cycles, minimizing wearand guaranteeing workpiece accuracy. Key products include:
Guide Pins (GP):
Cylindrical/stepped shafts (diameter 3mm -10omm, tolerance IT4 - IT7) withtapered lead-ins, made of GCr15 (HRC 58 - 62) or 40CrNiMoA for heavy-duty use.
Guide Bushings (GB):
Hollow components (inner diameter 3. 1mm -101mm) in bronze (CuSn10Pb10),GCr15, or seIf-lubricating graphite-impregnated bronze, reducing firiction by 40% vs. steel.
Guide Post Assenblies (GPA):
Pre-assembled sets with dust caps (NBR rubber) and retaining rings, ideal for large molds (e.g, refrigerator door panel molds).
Locating Components
Secure consistent workpiece positioningto el iminate dimensional variation,critical for precision applications(tolerance 0. 01mm). Main products:
Locating Pins (LP):
Cylindrical, conical (taper ratio 1:50), ordiamond-shaped sets, made of GCr15 (HRC 55 -60)or SKD11 (HRC 60- 63) for high wear resistance.
Locating Blocks (LB):
Rectangular/custom-shaped blocks (10X10X5mm-300X200X50mm) in 40Cr, Cr12MoV, or 316 stainless steel (corrosion-resistant).
Positioning Rings (PR):
Circular rings (outer diameter 50mm -300mm) matching injection machine nozzles,with fixed/floating designs to prevent resin leakage.
Ejection Components
Enable damage-free workpiece removal from mold cavities, bui It for high durabil ity(100,000+ cycles). Key items:
Ejector Pins (EP):
Straight, stepped, shoulder, or blade-type pins (diameter 1. 5mm-30mm) in SKD11 (HRC 60-63), H13 (for high temps), or DC53 (high toughness). Surface treatments include DLC coating (anti-adhesion)or TiAIN PVD (up to 800C resistance).
Ejector Sleeves (ES):
Hollow sleeves (inner diameter 2mm-35mm) for cylindricalworkpieces, ensuring 0. 005 -0. 01mm clearance with core pins.
Ejector Plates (EP):
Plates (100X100X10mm-1000X800X30mm) in 45# steel or S50C,with guided alignment (coaxiality 0. 01mm) for synchronized ejection.
Auxiliary Components
Support mold functionality, safety, and Iongevity. Key accessories:
Mold Springs (MS):
Compression, extension,
torsion, or Belleville springs in 65Mn (100k+ cycles),50CrVA (1M+ cycles), or Inconel 718 (high temps 650C).
Sealing Rings (SR):
O-rings, U-cups, orX-rings in NBR (oil-resistant), FKM (200C+), silicone (FDA-compliant), or PTFE(chemical-resistant).
Stopper Pins (SP):
Impact-resistant pins(diameter 5mm -30mm) in 40CrNiMoA ortungsten carbide, preventing overtravel damage.
