Designed to comply with Cumsa RCM series standards (UNE-EN 20283), the RCM Cumsa Standard Mold Component Slide Retainer is a premium-grade solution for securing sliding cores in injection moulds, combining Spanish engineering precision with global compatibility. Manufactured from corrosion-resistant stainless steel (AISI 304) or hardened tool steel (1.2316), this retainer ensures reliable core guidance in high-moisture or high-temperature applications, such as food packaging, medical devices, and automotive components. The modular design features quick-release tabs for easy maintenance, while the precision-ground guide rails eliminate play, ensuring repeatable core positioning and reducing scrap rates in high-volume production.
1. Cumsa RCM Standard Compliance: Meets UNE-EN 20283 for dimensional interchangeability with Cumsa mould systems, including RCM-15, RCM-20, RCM-25 models. The retainer body is marked with the Cumsa logo and part number for authenticating compatibility.
2. Dual-Material Construction: Choose between AISI 304 stainless steel (for corrosion resistance in medica applications) or 1.2316 tool steel (for high-temperature resistance up to 200°C/392°F in engineering plastics). Both materials are certified RoHS and REACH compliant.
3. Zero-Play Guidance System: The retainer features a twin-guide rail design with adjustable gib strips, allowing fine-tuning of core alignment (tolerance ±0.003mm) to eliminate lateral movement during injection, critical for parts with tight dimensional requirements.
4. Quick Maintenance Design: Spring-loaded retainer clips allow removal of the guide pin without disassembling the mould, reducing downtime during routine lubrication or wear inspection. A visual wear indicator turns red when guide rail tolerance exceeds 0.01mm.
5. Load Rating and Speed: Supports vertical/horizontal slides with maximum load capacities: 3kN (RCM-15), 5kN (RCM-20), 8kN (RCM-25), operating smoothly at slide speeds up to 400mm/s.
• Food Packaging Moulds: Secures slides in PP/PET tray moulds, resisting moisture and detergent exposure in automated packaging lines.
• Medical Device Production: Used in PVC/ABS syringe moulds to ensure sterile core movement, compliant with FDA 21 CFR Part 177 for indirect food contact.
• Automotive Interior Moulding: Guides slides in TPO/PU door trim moulds, maintaining core position during high-pressure injection (80-150 bar).
• Aerospace Component Moulds: Suitable for thermoplastic composites (e.g., PEEK, PEI) requiring precise slide control in high-temperature moulds (180°C/356°F).
Q: Is the stainless steel version suitable for saltwater environments?
A: Yes, AISI 304 offers moderate corrosion resistance; for marine applications, upgrade to 316L stainless steel (available as a custom option).
Q: How do I adjust the gib strips for core alignment?
A: Use the provided 2mm Allen key to turn the adjustment screw on the retainer body, tightening until minimal play is felt, then back off 1/4 turn for free movement.
Q: What is the difference between RCM and non-RCM slide retainers?
A: RCM retainers feature a unique locking notch compatible with Cumsa ejector plates, ensuring foolproof installation and preventing rotational misalignment.
Q: Can these retainers be retrofitted to non-Cumsa moulds?
A: Yes, with adapter plates (sold separately) that convert the mounting pattern to DME or HASCO standards, available in 15mm, 20mm, 25mm guide diameters.
Q: What is the warranty for wear-related defects?
A: We offer a 2-year warranty on material defects and machining precision, with discounted replacement parts available for normal wear after the warranty period.
