Engineered to meet global mould manufacturing standards (ISO 16906:2016), the China Manufacture International Standard Precision Mold Slide Retainers are high-precision components designed to secure and guide sliding cores in injection, compression, and die-casting moulds. Crafted from premium tool steel (SKD61, HRC 52-56) with the precision machining, these retainers ensure smooth linear motion of slide cores, preventing misalignment and improving part quality in complex mould geometries. The standardized design complies with international norms (DME, HASCO, LKM), enabling seamless integration into global mould setups, while the anti-wear coating enhances durability in high-temperature, high-pressure environments. Ideal for automotive, medical, and consumer goods industries, these retainers balance precision, reliability, and cost-effectiveness, making them a preferred choice for high-volume production.
1. International Standard Compliance: Meets ISO 16906:2016 for dimensional accuracy (tolerance ±0.005mm) and load-bearing capacity, compatible with major mould bases (DME-MEGA, HASCO Z18, LKM LSG). Available in standard sizes: 15mm, 20mm, 25mm guide diameters.
2. High-Precision Construction: The retainer body and guide pin are ground to a surface roughness of Ra 0.2μm, minimizing friction and ensuring smooth slide movement at speeds up to 500mm/s. A self-lubricating groove on the guide surface reduces maintenance by retaining grease for 50,000+ cycles.
3. Durable Anti-Wear Design: Heat-treated SKD61 steel with a TiCN coating (2-3μm thickness) resists abrasion from glass-filled polymers and frequent sliding motions, extending service life by 30% compared to uncoated retainers. The corrosion-resistant finish is ideal for humid or chemically aggressive environments.
4. Easy Installation: Pre-lubricated and pre-assembled, the retainer mounts to the mould base via counterbored holes (ISO 7380 metric threads), requiring only a torque wrench for installation (recommended torque: 25-40 N·m based on size).
5. Load-Bearing Stability: Designed to withstand lateral forces up to 5kN (for 25mm diameter), the retainer features a dual-lock spring mechanism that secures the slide core during injection, preventing flash formation and ensuring consistent part dimensions.
• Injection Moulding of Automotive Parts: Secures sliding cores in bumper moulds, door panel inserts, and headlight housings, enabling complex undercut geometries.
• Medical Device Moulds: Used in syringes, IV connector moulds to guide precision slides, meeting ISO 13485 requirements for zero-particulate contamination.
• Consumer Electronics Moulding: Ensures smooth slide movement in smartphone case moulds, laptop hinge components, and camera lens housings with tight tolerances (±0.01mm).
• Die Casting of Metals: Guides slides in aluminum die-casting moulds for automotive engine parts, reducing wear from high-temperature molten metal exposure.
Q: Can these retainers be used with non-ISO standard moulds?
A: Yes, adapters are available to convert mounting threads (e.g., NPT to M metric) for compatibility with North American or Japanese mould systems.
Q: What is the recommended lubrication interval?
A: Re-lubricate with high-temperature grease (NLGI 2) every 10,000 cycles or when friction increases, using the built-in grease nipple for easy application.
Q: Do you offer custom lengths for special mould thicknesses?
A: Yes, retainer lengths can be customized from 50mm to 300mm in 1mm increments, with no minimum order quantity for standard sizes.
Q: How does the TiCN coating affect slide speed?
A: The low-friction coating reduces sliding resistance by 20%, allowing faster cycle times without compromising positional accuracy.
Q: Are these retainers suitable for high-cavity moulds?
A: Yes, the standardized design ensures uniform performance across multi-cavity setups, with each retainer individually serialized for traceability in quality control.
