Hello everyone, this is Sunny. Today I will show you the two-color flip cap mold for shampoo independently designed and manufactured by our factory. We customize molds for shampoo, body wash, hair conditioner and other daily chemical packaging brands.
Many daily chemical brands want differentiated packaging, while single-color caps look too similar on the market. Two-color products made by painting or secondary assembly come with high costs and are prone to peeling and delamination. Our rotary two-color mold forms double-layer two-color caps in one injection cycle, which perfectly solves the pain points of the industry.

1. Core Technology of This Two-Color Shampoo Cap Mold

This mold supports PP+PP two-color materials and adopts a 180° rotary table two-color injection molding process:
  1. The first injection forms the threaded base of the cap. The precise thread fits tightly with the bottle to prevent leakage of washing liquid.
  2. The mold rotary table rotates 180 degrees accurately and transfers semi-finished products to the second injection station.
  3. The outer colored PP is overmolded in the second shot. The two layers of plastic fuse tightly under high temperature inside the mold without splicing gaps, so they will not separate or peel off after repeated opening and closing for a long time.

2. Advantages of Mold Structural Design for Stable Mass Production Without Defects

  1. Smooth Ejector Pin Demolding System

    The mold cavity adopts a professional ejector pin ejection design for gentle and smooth demolding. It fully protects the integrated hinge of the cap without breaking the flip top or scratching the product surface. Finished products have a flawless smooth surface free of bubbles, sink marks, weld lines and other appearance defects, requiring no secondary polishing.

  2. High-Durability Mold Steel for Long-Term Stable Production

    Core and cavity are made of high-polish pre-hardened mold steel, and the mold base is standard P20H steel. It delivers excellent mirror polishing performance and high wear resistance. The high-gloss finish can be maintained even after millions of production cycles, greatly reducing mold maintenance frequency.

  3. Complete Spare Parts Included for Trouble-Free Shipment

    Before delivery, we will provide a full set of spare parts together with the mold. Customers do not need to purchase extra replacement parts during later production, lowering long-term production costs.

3. Applicable Products & Customization Scope

This mold is specially designed for daily chemical flip caps, including shampoo caps, body wash flip tops, body lotion caps and hair conditioner packaging lids.

We also offer custom two-color molds for all kinds of daily plastic products. We can develop molds according to your requirements for caps, storage boxes, plastic handles, daily use housings and any products that need two-color layered appearance.
