Designed to meet HASCO Z43.1 standards for injection mould components, the German Hasco Standard Injection Plastic Mold Air Valve is a premium solution for precise air flow control during part ejection, ensuring damage-free and improved mould efficiency. This air valve integrates seamlessly with HASCO mould bases and hot runner systems, featuring a compact design and high-temperature resistance that makes it ideal for demanding applications in automotive, medical, and packaging industries. The valve’s precision-engineered poppet mechanism and leak-proof seals ensure reliable performance across millions of cycles, reducing downtime and enhancing production quality.
1. HASCO Z43.1 Compliance: Matches HASCO’s dimensional and functional specifications, enabling direct replacement of existing Z43.1 valves without modifications. Available in standard sizes: Z43.1-6, Z43.1-8, Z43.1-10 (orifice diameters 6mm, 8mm, 10mm).
2. High-Pressure Air Control: A hardened steel poppet with a PTFE-sealed seat regulates air pressure from 0.3–15 bar, suitable for both lightweight plastics (e.g., PE) and engineering polymers (e.g., PA, POM). The valve opens within 30ms of receiving an ejection signal, creating a uniform air gap for smooth part release.
3. Temperature-Resistant Construction: The body (1.2316 tool steel) and spring (music wire with nickel plating) withstand mould temperatures up to 220°C (428°F), while FKM seals ensure elasticity and airtightness in high-heat environments.
4. Leakage Prevention Design: Double O-ring seals (primary and secondary) and a pressure-balanced poppet reduce leakage to <0.1% of rated flow, even at maximum operating pressure. The valve’s surface is polished to Ra 0.8μm to prevent plastic residue buildup.
5. Modular Maintenance Kit: Includes replacement seals, springs, and poppet tips for on-site servicing, with a maintenance schedule based on cycle count (recommended every 200,000 cycles for high-speed moulds).
• Automotive Moulding: Critical for ejecting large, complex parts like instrument panels and bumpers without warping or surface defects.
• Medical Device Production: Ensures gentle ejection of precision components (e.g., insulin pen parts, labware) that require zero surface marring, meeting ISO 13485 cleanliness standards.
• Packaging Moulds: Used in thin-walled container moulds to eliminate vacuum retention, enabling high-speed production of food trays and cosmetic packaging.
Q: Can this valve be used with non-HASCO moulds?
A: Yes, adapters are available to mount the valve on DME, LKM, or other non-HASCO mould bases. Contact our engineering team for custom mounting solutions.
Q: What is the difference between the Z43.1-6 and Z43.1-10 valves?
A: The number indicates the orifice diameter (6mm vs. 10mm), affecting maximum air flow rate—choose based on part size and material: smaller orifices for thin parts, larger for thick/wide components.
Q: How does the valve integrate with mould control systems?
A: It connects to the mould’s ejector plate via a threaded mount and is activated by a proximity sensor or PLC signal, synchronizing with the ejection cycle for precise timing.
Q: Can the valve handle abrasive materials like glass-filled nylon?
A: Yes, the hardened steel poppet and PTFE seat resist wear from filled polymers. For highly abrasive materials (e.g., carbon fiber composites), consider our tungsten carbide-tipped variant (custom order).
Q: Is the valve compatible with hot runner systems?
A: Yes, it can be installed in both hot runner and cold runner moulds, with thermal insulation options available for proximity to hot runner manifolds (up to 300°C/572°F).
