Laundry Basket Injection Mold - Deep Cavity Ventilated Household Storage Plastic Tooling

Laundry baskets and hampers are widely‑used household storage items for bedrooms, bathrooms and laundry rooms. Typically produced from PP or HDPE, these deep‑cavity containers feature load‑bearing side walls, ventilated hollow perforations and ergonomic handles for comfortable carrying.

Molding these large deep‑draw parts brings noticeable tooling challenges. High in‑mold pressure, long melt‑flow distance and extensive cut‑out features can easily create weld lines, warpage, gas trapping and poor demolding performance. Improper gating, cooling or parting‑line arrangement will directly lower mass‑production yield.

Professional Gating & CAE Optimization
To balance filling pressure and avoid molding defects, we arrange gates on thick wall areas to guide melt flowing from thick sections to thin hollow areas. This method effectively reduces injection pressure and clamping force requirements. All filling balance, flow trace and weld line positions are verified by pre‑production CAE simulation to ensure stable and consistent molding quality for long‑term mass production.

Core Mold Engineering Technology
We adopt optimized parting line layout at the bottom edge instead of the middle surface, greatly improving the demolding success rate and avoiding flash on visible surfaces. Advanced conformal cooling channels shorten cooling time and reduce product deformation caused by uneven temperature distribution. Reasonable venting around hollow inserts eliminates burning marks and short shots. Multi‑point balanced ejection protects thin ribs and perforation edges from whitening or cracking during demolding.

High‑Standard Surface Finishing
We provide high‑end cavity surface treatment for laundry basket molds. The mirror polishing process reaches Ra ≤ 0.8μm, ensuring ultra‑smooth surface that prevents clothes from snagging and improves product texture. It can be matched with custom texture, rattan grain and logo etching to realize diverse appearance grades for retail market differentiation.

With over 25‑year experience in mold manufacturing and injection molding at Vios, we support full customization of mainstream laundry basket types to fit different market demands, including open ventilated laundry baskets, rattan‑textured hampers, lidded dirty clothes bins, stackable storage baskets and lightweight optimized household baskets. All structural details such as ergonomic handle curvature, hollow hole distribution and stacking tolerance are strictly customized based on client 3D files.

Apart from laundry basket and hamper molds, we customize various large deep‑cavity household plastic molds such as storage bins and waste bins. Our one‑stop service covers DFM analysis, structural optimization, CAE simulation, precision machining and full trial molding support.
