· Product Overview

· Core Specifications

• Materials:
  • Hook Body: High-strength ABS Plastic (shock-resistant, wear-resistant, and suitable for indoor/outdoor dry environments).
  • Torsion Spring: High-Carbon Steel (with rust-resistant coating, optimized for consistent retraction force).
• Manufacturing Standard: ISO 9001-Certified Production Process
  • Plastic Hook: Injection molding (complies with ISO 1043-1 for plastic mechanical performance) + edge trimming (for smooth, burr-free surfaces).
  • Torsion Spring: Cold coil winding + heat tempering (for stable elasticity) + anti-rust coating (enhances corrosion resistance).
  • Key Performance: Max hanging load: 2kg; spring retraction cycle: ≥5,000 times (without force degradation).

· Application Scenarios

• Bathrooms: Hanging towels, bath sponges, or shower accessories (self-retracting design keeps the area tidy).
• Kitchens: Storing cooking utensils, pot holders, or small cleaning tools.
• Entryways & Closets: Hanging keys, hats, scarves, or small garments.
• Furniture Accessories: Integrated into cabinet doors, wardrobe interiors, or storage box lids for built-in hanging functionality.
• Office Spaces: Organizing lanyards, headphones, or small stationery items.

· Production Process Introduction

1. Mold Design & Fabrication: Create precision injection molds for the ABS plastic hook body (matching the curved shape and mounting interface).
2. Plastic Injection Molding: Inject molten ABS plastic into molds, then cool and demold to form the hook body; trim edges to remove burrs.
3. Spring Production: Wind high-carbon steel wire into torsion springs via automated machines, then temper (to stabilize elasticity) and apply rust-resistant coating.
4. Component Assembly: Insert the torsion spring into the plastic hook body, then test the retraction function to ensure smooth operation.
5. Quality Inspection: Verify hook load capacity, spring retraction smoothness, and plastic surface integrity; reject defective units.

· Packaging and Shipping Methods

• Packaging: Individual hooks are sealed in transparent OPP self-sealing bags (for dust protection); bulk orders are packed in reinforced cartons with partitioned layers (to prevent hook deformation or surface scratches during transit).
• Shipping: Flexible logistics options:
  • Express Delivery (DHL/FedEx/UPS: 3–5 business days)
  • Air Freight (7–10 business days)
  • Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 sets per standard design; small sample packs (10–20 sets) are available for usability testing.
• Lead Time: Standard lead time is 7–10 working days after order confirmation; expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—we can adjust the hook size, plastic color (e.g., white, gray), spring retraction force, or add mounting adhesive to the back, based on your technical requirements. Our engineering team will validate design feasibility.
