# Custom Basket Systems + Heat-Resistant Kitchen Components | Injection Molding Solutions

Applications: Air fryer baskets, steamer baskets, draining baskets, oven racks, dishwasher baskets, and modular basket assemblies (featuring snap-fits, sliding rails, or stackable designs). All these components are intended for use in environments involving **food contact, high-heat exposure, frequent washing, and contact with oils/fats**. Key technical challenges include: high-density perforation, thin-wall geometry, weld line management, warpage control, and regulatory compliance regarding material leaching/migration. ## I. Material Selection (Categorized by Temperature & Cost)

>

> Export Compliance Standards: GB 4806.6, FDA 21 CFR, and EU (No.) 10/2011. Documentation required: Manufacturer-issued TDS (Technical Data Sheet), COA (Certificate of Analysis), and migration test reports.

1. **High-Heat-Resistant Food-Grade PP (Mainstream, Cost-Effective Choice)**

- Examples: Borouge RD265CF or similar β-crystalline high-heat-resistant PP; Heat Deflection Temperature (HDT) @ 1.8 MPa ≈ 135°C.

- Applications: Steaming baskets, colanders, air-fryer components (non-direct-contact), and microwaveable parts. Offers excellent resistance to steam and oil, with good moldability.

- Molding Considerations: Drying is optional (due to low moisture absorption); maintain a mold temperature of 40–70°C to prevent post-molding shrinkage and warpage.

2. **PA6/PA66 + GF (Glass Fiber Reinforced – for load-bearing baskets, latches, and pivots)**

- Applications: Heavy-duty baskets, frequently engaged/disengaged latches, and sliding rails. Suitable for long-term use at 120–150°C; provides high rigidity.

- Risks: Hygroscopic (requires thorough drying); potential for glass fiber exposure and mold abrasion. Must use food-grade modified resin grades.

3. **PPS (Polyphenylene Sulfide – Primary Choice for High-Temperature Environments)**

- Withstands continuous temperatures of 180–220°C; resistant to oils and detergents, with low extractables/leachables. The preferred material for air-fryer baskets (direct-contact/baking) and internal oven components.

- Processing: Requires high temperatures (barrel: 300–340°C); necessitates the use of hot-work tool steel for molds; recommended mold temperature: 120–160°C.

4. **LCP / PEI / PEEK (High-End, Extreme-Condition Applications)**

- LCP: Ideal for thin-walled, porous components; offers excellent flow and low warpage. PEI (Ultem): Suitable for transparent or translucent heat-resistant parts. PEEK: Primarily used in high-end commercial equipment.

- High cost; primarily used for commercial kitchen appliances and industrial-grade baskets.

>

> Basket systems often consist of a **multi-material assembly**: a basket body made of PP or PPS, connecting clips made of PA, and silicone seals.

## II. Key Points for Product Structural Design (Specific to Baskets)

Baskets are characterized by complex, interwoven structures—comprising numerous grids, through-holes, thin walls, and ribs—which are highly susceptible to issues such as short shots, weld line fractures, stress marks (whitening) at ejector pin locations, deformation during demolding, and tolerance stack-up errors.

1. **Uniform Wall Thickness**: Ideally 1.2–2.0 mm. Avoid abrupt changes in thickness for grid ribs. Use a corner radius (R) of ≥0.5 mm to minimize stress concentration.

2. **Aperture and Rib Layout**: Align the material flow with the primary ribs. Ensure that weld lines are positioned in areas not subject to significant stress. Increase the width and height of critical load-bearing ribs, and avoid placing load-bearing features directly on weld lines.

3. **Modular Basket Systems**

- Incorporate features for stacking alignment, guide angles, snap-fits, and anti-tip/locking mechanisms. For undercuts (locking features), prioritize the use of lifters or slides.

- Account for material shrinkage when determining fit clearances: PP shrinks by approximately 1.5–2.0%; PPS+GF by ~0.4–0.8%; and PA+GF by ~0.6–1.0%.

4. **Draft Angles**: Use a draft angle of ≥1.5° for visible surfaces, and ≥2° for the inner sides of grids and rib locations. In areas with dense, numerous holes, increase the draft angle to prevent the part from sticking to the mold or developing stress marks (whitening) during ejection.

5. **Venting Provisions**: The ends of grid segments and areas where weld lines form are prone to trapped air; ensure that the mold design includes adequate venting in these locations.
