1+2 Cavity Injection Plastic Mold for Make up Container Covering Body PA6 ABS PP Material

This specialized 1+2 cavity injection mold is engineered for manufacturing makeup container components—specifically 1 piece of cover + 2 matching body parts (e.g., lipstick tube caps, powder box lids, foundation bottle bodies) in one production cycle. Optimized for PA6, ABS, and PP plastics (the most widely used materials in cosmetic packaging), it balances precision, efficiency, and aesthetic performance. The mold delivers defect-free, glossy-finish components that meet cosmetic industry standards (non-toxic, scratch-resistant, and color-stable), making it ideal for cosmetic brands, packaging manufacturers, and beauty product startups seeking cost-effective, high-volume production.

Product Overview

This specialized 1+2 cavity injection mold is engineered for manufacturing makeup container components—specifically 1 piece of cover + 2 matching body parts (e.g., lipstick tube caps, powder box lids, foundation bottle bodies) in one production cycle. Optimized for PA6, ABS, and PP plastics (the most widely used materials in cosmetic packaging), it balances precision, efficiency, and aesthetic performance. The mold delivers defect-free, glossy-finish components that meet cosmetic industry standards (non-toxic, scratch-resistant, and color-stable), making it ideal for cosmetic brands, packaging manufacturers, and beauty product startups seeking cost-effective, high-volume production.

Core Advantages: Cosmetic-Grade Precision & 1+2 Cavity Efficiency

1. Premium Materials for Durability & Aesthetic Results

  • Mold Base: 4Cr13 Stainless Steel – Corrosion-resistant, rigid, and supports 800,000+ injection cycles; compatible with cosmetic production environments (easy to clean and maintain).

  • Cavity & Core: ASSAB S136 ESR Steel – Vacuum heat-treated to HRC 52-54, offering exceptional wear resistance against PA6/ABS/PP flow; polished to Ra 0.01μm mirror finish – Ensures the mold’s surface transfers to the container (glossy, smooth, and free of burrs/scratches, eliminating the need for post-processing).

  • Anti-Stick Coating: PTFE-coated cavity surfaces – Prevents plastic adhesion during ejection, especially critical for ABS (prone to sticking) and ensures clean, intact cover/body parts.

  • Material Compatibility: Tailored flow channels and temperature control for PA6 (230-260℃), ABS (220-250℃), and PP (200-220℃) – Ensures uniform filling, strong structural integrity, and no material degradation (non-toxic, meets EU REACH and FDA cosmetic packaging standards).

2. 1+2 Cavity Design: Balanced Efficiency & Flexibility

Cavity Layout & Production Capacity

Component Combination Cavity Allocation Daily Output (8-Hour Shift) Application Scenario
1 Cover + 2 Body Parts 1 cover cavity + 2 body cavities (integrated mold) 8,000-10,000 sets (16,000-20,000 total parts) Lipstick tubes, mascara bottles, small powder boxes (1:2 component ratio).
Custom 1+2 Combination 1 main component + 2 auxiliary parts (e.g., 1 lid + 2 inner liners) 7,000-9,000 sets Foundation bottles, blush containers (with removable inner trays).

Key Design Features for Cosmetic Containers

  • Aesthetic Precision: Uniform wall thickness (1.2-2.0mm) with tolerance ±0.03mm – Prevents warping or shrinkage, ensuring consistent fit between cover and body (no loose or tight closures).

  • Snap-Fit/Threaded Structures: Precision-machined snap grooves or internal threads (for screw-on covers) – Ensures secure closure and easy opening (tested to 5,000+ opening/closing cycles without failure).

  • Logo & Texture Integration: Molded embossing/debossing for brand logos (minimum 0.3mm depth for clear visibility) or surface textures (matte, grainy, or metallic finish simulation) – Enhances product premium 感.

  • Cooling System: 360° spiral cooling channels for cover cavities + grid cooling for body parts – Reduces cycle time to 22-28 seconds per set and maintains consistent temperature (±2℃) – Critical for glossy surface finish.

  • Ejection System: Soft-eject pins with rounded tips – Avoids indentations or scratches on visible surfaces of the cover/body.

3. Quality & Compliance for Cosmetic Packaging

  • Safety Certifications: Mold materials and production processes meet EU REACH (Restriction of Hazardous Substances), FDA 21 CFR Part 177 (food-contact safe for cosmetic containers), and ISO 9001 standards.

  • Strict QC Protocols:

    • 72-hour continuous cycle testing with PA6/ABS/PP materials to verify stability and surface finish.

    • 100% dimensional inspection via CMM (focus on cover-body fit, wall thickness, and logo clarity).

    • Visual inspection for defects (no air lines, discoloration, or burrs) – 0% defect rate for finished components.

  • Color Consistency: Optimized flow channels ensure uniform plastic distribution – Prevents color variation across batches (critical for cosmetic packaging brand consistency).
