Two-Color Shampoo Cap Mold Real Shot | One-Stop Custom Manufacturer of Daily Chemical Two-Color Molds

Leave a comment
Click the link to watch the complete trial run video of this shampoo cap mold.
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.

4. Full-Service Mold Solutions From Our Factory

As a professional two-color mold manufacturer, we provide one-stop full mold development service:
  1. Pre-production: DFM manufacturability analysis and mold flow simulation based on customers’ product drawings or samples to avoid mass production risks such as sink marks, deformation and air trapping in advance.
  2. Production stage: CNC machining, precision polishing and mold assembly. Multiple trial runs on our in-house two-color injection machines, with full trial videos and finished samples provided.
  3. After delivery: The mold is packed and shipped with complete spare parts. We offer lifetime remote technical guidance and mold warranty & maintenance support.

5. Cooperation Invitation for Daily Chemical Packaging Manufacturers

If you are a daily chemical brand, packaging factory or injection molding processor who wants differentiated two-color caps to boost product competitiveness, feel free to contact us anytime.

We can customize exclusive two-color molds based on your product size, cavity quantity and material requirements, provide accurate quotations and molding solutions, and look forward to long-term stable cooperation.

A two-color pepper shaker flip cap mold integrates two different colored PP materials into one finished seasoning lid in a single molding cycle.
The inner structural part adopts solid PP for stable structure, food-grade safety and excellent chemical resistance against seasonings.
The injection machine has a 280-ton clamping force and rotary table.
After the first shot of solid PP molding, the rotary table rotates the semi-finished inner part to the second injection station.
Then transparent PP material is overmolded onto the outer surface of the preform.
This rotary two-color injection process forms tight seamless bonding between the two PP layers, effectively preventing separation or peeling during daily repeated opening and closing.
We select 1.2344 pre-hardened steel for core and cavity, with P20H steel for the whole mold base.
This steel grade delivers superior mirror polishing performance, high wear resistance and consistent uniform hardness.
It extends long mold service life and maintains stable high-gloss surface finish for every transparent PP cap without scratches.
The double 8-point hot runner system balances plastic filling evenly across all 16 cavities, ensuring identical product weight and appearance for each lid.
It eliminates wasteful cold runner material and greatly improves the glossy surface quality, reducing visible weld lines and sink marks on transparent parts.
Cooling channels are professionally optimized to shorten molding cycle time and stop product warpage & deformation after ejection.
Full vent slots are reasonably distributed along the mold parting line to exhaust trapped air, avoiding burnt marks or bubbles on the transparent PP surface.
Every mold structure, sleeve ejection system and hot runner layout is fully validated via DFM report and Moldflow simulation before CNC machining, to manufacture safe, food-contact compliant, durable flip-top pepper caps for daily condiment packaging.
At YUEYI, we specialize in custom high-cavity two-color daily plastic packaging molds, delivering full turnkey solutions including DFM analysis, moldflow simulation, mold manufacturing, trial testing and lifetime technical after-sales support.
If you have similar two-color plastic cap & packaging mold projects, please contact us for detailed quotation.
We welcome all mold inquiries and look forward to building long-term win-win cooperation with you.
