Garden Machinery Mould
Garden machinery components—including lawn mower housings, pump bodies, and structural enclosures—demand a unique combination of large-scale dimensional accuracy, robust structural integrity, and weather-resistant durability. These components must withstand outdoor operating conditions, mechanical vibration, and long-term UV exposure while maintaining precise fit and function across complex multi-part assemblies. Sino Mould brings over 20 years of injection moulding expertise to garden machinery mould manufacturing, delivering high-precision, high-efficiency tooling solutions for lawn mower components, water pump housings, and related outdoor power equipment applications. Our proven track record includes multiple mould deliveries for industry-leading customers such as AL-KO, demonstrating our capability to meet the most demanding quality and performance standards.

Key Quality Points of Garden Machinery Moulds
- Large-format precision & dimensional stability: DIN 1.2738 steel and high-rigidity mould base ensure precise core/cavity alignment for moulds up to 1200mm; part dimensional tolerance ±0.1mm.
- Thin-wall filling integrity: Mould flow analysis optimizes gate location and rib thickness design, eliminating short shots in thin rib areas and ensuring complete filling.
- Efficient cooling & short cycle: Strategically routed cooling circuits optimized for deep cores and thermal hot spots achieve a stable 40s cycle (cooling time 50%-60% of total cycle).
- Excellent surface quality: Superior polishability of 2738 steel combined with precision finishing (Ra≤0.05μm) eliminates scratches, flow marks, and sink marks for visible exterior parts.
- Reliable mark-free ejection: Balanced ejector pin system ensures uniform force distribution across large parts for smooth, deformation-free release with no ejector marks.
Precision Machining Highlights for Garden Machinery Moulds
- Heavy-duty equipment: Large gantry CNC (work range ≥1500mm), precision EDM, and deep-hole drilling for moulds up to 1200×850×700mm.
- High-accuracy inspection: Hexagon CMM verifies all critical dimensions; core/cavity mating precision ≤0.02mm.
- Cooling circuit machining: Deep-hole drilling and 5-axis machining for complex conformal cooling channels to rapidly cool deep core sections.
- Surface finishing: Mirror polish of cavity and laser-cut vents improve demoulding and melt flow.
- Assembly & testing: Experienced assembly team ensures precise tuning of hot runner and ejector systems; delivery within 70 working days.
Mould Flow Analysis for Garden Machinery Moulds
Mouldflow simulation for a typical lawn mower deck:
- Fill balance: Melt front advances uniformly; short shot risk areas have been optimized.
- Weld line position: Controlled to non-cosmetic and low-stress areas.
- After cooling optimization: Warpage ≤1.0mm, meeting assembly requirements.
- Clamp force prediction: Perfectly matched with DKM 850T; uniform injection pressure distribution.
