Key Quality Points of Baby Products Mould
SINOMOULD has over 20 years of experience in baby product moulds, supplying 30+ sets annually to global customers. We strictly adhere to the following standards:
01 Safety Materials & Compliance
- Core & cavity made of high-purity stainless steel like S136, 718H, corrosion-resistant and easy to polish, complying with FDA, EU 10/2011, LFGB food contact standards.
- Copper-free/lead-free materials for mould base and moving parts to prevent heavy metal contamination.
02 Mirror Polish & Burr-Free Design
- Cavity surface mirror polished (RA ≤ 0.05μm) ensuring ultra-smooth finish safe for baby skin.
- Precision ground parting lines and edges – zero burrs or sharp corners.
- All edges rounded to eliminate scratch risks.
03 Precision Moulding – Small Size, High Accuracy
- Baby products are typically small-sized with complex geometries (nipples, handles, snaps). Mould tolerance controlled within ±0.02mm.
- Electric injection machines or high-response hydraulic presses for precise pressure and speed control.
- Multi-cavity moulds (8/16/32 cavities) ensure cavity-to-cavity consistency for high-volume production.
04 Short Cycle & Efficient Cooling
- Conformal cooling channels designed for thin-wall (1.5-2.5mm) baby products, achieving uniform cooling and cycle time as low as 15-35 seconds.
- Precise temperature control (±1℃) prevents warpage, especially for high-temperature engineering plastics like PPSU and Tritan.
05 Advanced Hot Runner System
- Valve gate hot runner enables sequential injection, eliminating flow marks and weld lines.
- Nozzle tips made of wear-resistant carbide suitable for glass-fiber reinforced materials (e.g., PP+GF).
- Scrap-free production saves material cost (baby product materials are expensive).
06 Mould Flow Analysis & Trial Validation
- Mouldflow software simulates filling, packing, cooling, and warpage – identifying air traps and weld lines in advance.
- Scientific moulding during trial – systematically optimizing pressure, speed, temperature, and holding profiles.
- Continuous production test (≥5 hours) before shipment to verify stability.
Mould Flow Analysis for Baby Products Moulds
Using Mouldflow analysis, we optimize the filling, packing, and cooling processes of the centrifuge tube mould. The analysis simulates the injection moulding process, optimizing cavity layout, gate positions, and temperature control solutions, ensuring uniform cavity filling and reducing air pockets, warping, and short shots, enhancing the moulding stability of the centrifuge tube mould.
Baby products are typically small-sized, multi-cavity moulds. Mould flow analysis accurately identifies filling variations between cavities, guiding adjustments to runner dimensions or gate positions to achieve cavity-to-cavity consistency <2%.
