Four basket families, one tooling method

One engineering method, sized for different markets, loads and finishes.

Rattan-weave laundry basket mold

The rattan-weave laundry basket mold is an industrial mold used for injection-molding imitation rattan plastic laundry baskets. Through finely etched textures on the cavity surface, it gives the product a realistic rattan-weave appearance and a non-slip feel. With complex demolding structures such as side core-pulling or lifters, it integrally forms the basket base, body, and handles in one piece, combining the aesthetics of rattan weaving with the durability of plastic. Common materials include P20, 718, and S136 steel, with a molding cycle of approximately 43 to 45 seconds.

Round classic laundry basket mold

The round classic laundry basket mold is an industrial mold designed for injection-molding round imitation rattan laundry baskets. Its cavity features a circular symmetrical structure with finely etched surfaces that create a realistic rattan-weave texture. It typically uses a half-split slider (split mold) or rotary demolding structure to solve the demolding challenge posed by the hollow woven texture on the round basket body, allowing the base, body, and handles to be integrally formed in one piece. The finished product has a classic, versatile look that combines the natural beauty of rattan weaving with the lightweight durability of plastic. Common steels include P20, 718, and S136, with a molding cycle of approximately 43 to 45 seconds.

Classic rectangular laundry basket mold

The classic rectangular laundry basket mold is an industrial mold designed for injection-molding rectangular imitation rattan laundry baskets. Its cavity features a rectangular symmetrical structure with finely etched surfaces that create a realistic rattan-weave texture. It typically uses four-corner sliders (side core-pulling) or lifters to solve the demolding challenge posed by the hollow woven texture and corners of the rectangular basket body, allowing the base, body, and handles to be integrally formed in one piece. The finished product has a classic, practical shape that sits neatly against a wall, combining the natural beauty of rattan weaving with the lightweight durability of plastic. Common steels include P20, 718, and S136, with a molding cycle of approximately 43 to 45 seconds.

Other types laundry basket mold

In addition to the classic round and rectangular styles, other laundry basket molds are mainly categorized by product structure and functional design. Common types include: lidded laundry basket molds (requiring an additional independent lid mold or a dual-cavity structure for dust and moisture protection), handled laundry basket molds (using side core-pulling or lifters to form integrated handles), collapsible laundry basket molds (employing precision sliders and hinge inserts to form folding structures for easy storage and transport), perforated/mesh laundry basket molds (using numerous insert pins or core-pulling mechanisms to form holes with smooth walls), and bath bucket/storage basket dual-use molds (featuring a deeper body and larger capacity, requiring enhanced cooling and ejection systems to handle the molding and demolding of large-volume parts).

Workflow

Custom Laundry Basket Mold Development Process

From initial 3D conceptualization to final trial shot testing in our high-tonnage injection machines, our streamlined 6-stage process ensures total transparency.

Communication of requirements

Discuss the product dimensions, structure, appearance, material, mold steel requirements, injection machine tonnage, and other key information needed for product design.

Step 1

Technical Drawing Approval

The documents to be confirmed include: product 3D drawings, mold drawings, and any related drawings required for mold flow analysis, if applicable.

Step 2

Custom Materials & Mold Processing

Prepare the required steel according to customization needs, and arrange mold processing such as CNC machining, EDM, deep-hole cooling, polishing and texturing, as well as steel heat treatment.

Step 3

Trial Sample Approval

Conduct trial molding and send samples to the customer for confirmation, and keep improving the mold until the customer approves it as qualified.

Step 4

Shipment and Delivery

Prepare the mold 2D/3D drawings, inspection reports, etc., and customize wooden crates as required, arrange booking, and confirm the shipping schedule.

Step 5

After-sales Follow-up Service

Provide services such as rapid response, technical support, repair and maintenance, and spare parts supply for customers' mold usage.

Step 6

Engineering solutions

Tooling engineered for laundry basket geometry

Household, stackable, lidded and collapsible baskets fail in the same places: heat at the handle roots, sink in the base, stack lock-up, scuffed ejection.

√ Uniform Wall Thickness Control

Wall thickness across the basket body and base must transition evenly to prevent sink marks, deformation, and stress whitening, ensuring consistent appearance and load capacity.

√ Surface Texture and Polishing

High gloss, matte, leather grain, or rattan textures can be applied as required. The mold needs corresponding polishing or EDM processes to ensure clear, consistent texture.

√ Load-Bearing and Rib Design

Reinforcing ribs are typically added under the base and at the handle roots to improve load capacity and resistance to deformation, ensuring stability and durability.

√ Stacking and Fit Structure Design

For stackable baskets, the mold must precisely control stacking angle, fit clearance, and stack height to ensure stable stacking and easy storage and transport.

√ Parting Line and Demolding Optimization

Parting lines, sliders, and ejection systems are designed based on the basket body, base, and handle structure to ensure smooth demolding and avoid scratching or deformation.

√ Hinge and Assembly Structure Precision

For folding and separate-handle baskets, the mold must precisely control hinges, snap fits, assembly holes, and connection structures to ensure smooth folding, firm assembly, and stable use.

Spec Sheet

Configurable Mould Parameters

Typical ranges only. Final build follows part size, resin grade and target output. Part size determines mold structure and machine tonnage; resin grade determines steel and runner system; target output determines tool life and steel grade. Cooling, surface finish, lead time and budget should also be confirmed together.

Item	Options / Values	Notes
Cavity / Core Steel	P20, 718H, 2738, NAK80, H13, S136	Selected by tool life and polish requirements
Cavity / Core Hardness	Pre-hardened steel HRC 30–35; Heat-treated steel HRC 48–52	Directly affects wear resistance and mold life
Mold Base	LKM / HASCO / DME / MISUMI	LKM S50C or P20 are common choices
Runner System	Hot runner (pin-point gate) / Cold runner	Hot runner is common for chairs to reduce cold scrap and improve efficiency
Number of Cavities	Single cavity (large chairs) / Multi-cavity (stools)	Large chairs are usually 1-cavity; small parts can be multi-cavity
Resins	PP, HDPE, ABS, PC, regrind	PP is commonly used for chairs; UV-stable PP required outdoors; glass-filled resins need wear-resistant steel
Tool Life	300,000 – 1,000,000 shots	P20 approx. 200,000–300,000; 2738/heat-treated steel can reach 600,000–1,000,000
