I. Origin of Two-Color & Mixed-Color (Dual-Component) Injection Molding Machines

The birth of two-color and mixed-color (dual-component) injection molding machines stems from the plastic products industry’s demand for upgraded functionality, aesthetic quality, and production efficiency. They represent a key advancement in injection molding technology, shifting from "single-function" to "multi-functional integration".

In the era of traditional single-color machines, plastic parts could only be molded in one color and one material. Achieving two-color, multi-color, or composite effects required multiple injections, secondary processing, and assembly—leading to complex workflows, high labor costs, and quality issues such as seams, uneven coloring, and material delamination. These limitations failed to meet the demand for refined, integrated products.

As manufacturing became more automated and precise, driven by rapid growth in automotive, consumer electronics, and daily necessities industries, the market demand for two-color and mixed-color plastic products surged, forcing technological upgrades. In the mid-to-late 20th century, foreign manufacturers pioneered early two-color injection equipment, initially focused on distinct two-color molding for visual differentiation. With breakthroughs in plasticization and temperature control, machines evolved to support precise mixing and gradient effects between two colors or materials, giving rise to "mixed two-color injection molding machines".

China’s dual-component injection molding industry began in the late 20th century. Supported by booming domestic manufacturing, technology introduction, and independent R&D, it gradually broke foreign monopolies and transitioned from imitation to innovation, forming industrial clusters centered in Ningbo, Guangdong, and other regions. Enterprises such as Ningbo Konger Machinery Co., Ltd. have become industry benchmarks in dual-component injection molding through precise market positioning and technological innovation, driving the popularization and upgrading of domestic dual-component technology.

II. Market Demand for Two-Color & Mixed-Color (Dual-Component) Injection Molding Machines

The global manufacturing shift toward precision, sustainability, and high efficiency, combined with continuous upgrading of downstream industries, has driven steady growth in the market for dual-component injection molding machines.

Industry data shows that the global single- and dual-component plastic molding market reached $48.76 billion in 2024 and is projected to grow to $62.34 billion by 2029, with a CAGR of approximately 4.9%. The share of dual-component molded parts rose from 38.7% in 2020 to 42.3% in 2024 globally, and reached 45.1% in China, demonstrating strong market potential.

Demand is driven by three core factors:

1. Downstream Industry Upgrades Create Rigid Demand

Growth in automotive, consumer electronics, daily necessities, medical, and packaging sectors is the primary engine.

Automotive: The rise of new energy vehicles has boosted lightweight plastic components, with plastic usage per vehicle reaching 180–220 kg, an increase of 45–50%. Dual-component molding is widely used in interiors (steering wheels, dashboards, door panels) and exteriors (logos, bumper trims), combining personalized appearance with anti-slip and wear-resistant functions.

Consumer Electronics: 5G phones and wearable devices drive demand for precision dual-component parts such as phone casings, earphone shells, and watch bands, using mixed-color processes for gradients and textures.

Daily Necessities: Thermos cups, toys, and kitchenware use dual-component molding for color splicing and gradients to meet aesthetic preferences.

Medical: Syringes and infusion sets benefit from "functional layer + safety layer" composite molding, improving usability and safety.

2. Demand for Higher Efficiency and Cost Control Drives Equipment Upgrade

Compared with traditional single-color injection plus secondary processing, dual-component machines enable one-step molding, eliminating assembly and painting. This shortens cycles and improves efficiency by 30–50%, while reducing labor costs.

High-performance machines allow precise material ratio control. Technologies such as Konger’s True Sandwich Molding enable the combination of virgin and recycled materials, maintaining quality while reducing material waste—a key reason SMEs are replacing traditional equipment.

3. Environmental Policies Accelerate Technological Upgrades

Strict global environmental regulations—including EU REACH, RoHS, and China’s New Material Industry Development Guide—push the industry toward green and low-carbon production. Dual-component machines reduce waste via one-shot molding and support bio-based and recyclable materials, further boosting market demand.
