Konger CMS Color Mixing Injection Molding System: Breaking Traditional Two-Color Boundaries, Creating High-End Artistic Textures
In the injection molding industry, traditional two-color machines primarily focus on achieving sharp, distinct two-color effects. In contrast, the Konger CMS Color Mixing System centers on unique effects such as two-color gradients, marble patterns, cloud patterns, and inner sandwich layers. Tailored to customer requirements, it enables diverse and personalized two-color and multi-color mixing molding, making it the preferred solution for high-end injection-molded products.
I. Core Technical Principles
The CMS series is fundamentally different from traditional two-color injection molding machines. Relying on a dedicated color-mixing nozzle and precision dual control systems, it achieves distinctive artistic texture molding:
Chameleon Dynamic Effect: By precisely controlling the pressure and speed of two or three injection systems, the melts of two color materials form controllable turbulence before entering the mold, naturally presenting artistic textures like marble patterns and streamline patterns on the product surface.
Unique Texture: Each finished product features a naturally formed, one-of-a-kind texture, granting strong market competitiveness in high-end daily necessities, cosmetic packaging, stationery, and other fields.
II. Core Model Categories
CMS Classic Two-Color Basic Model: Equipped with an A+B dual injection unit configuration, it meets mainstream two-color mixing requirements with wide applicability.
CMS-3Color Flagship Three-Color Model: Capable of naturally interweaving three colors simultaneously. It features high technical barriers, and only a few manufacturers in China can achieve stable mass production of this model.
III. Core Selling Points
High-Pressure Injection Stability: Color mixing injection molding requires micron-level precision in back pressure and injection position; minor errors can disrupt textures. The CMS series is fitted with a high-performance servo system for outstanding stability.
Targeted Screw Design: Optimized for screw length-to-diameter ratio (L/D) and compression ratio to resolve pigment agglomeration and uneven mixing, ensuring uniform and stable melt color blending.
Strong Mold Compatibility: Unlike clear two-color processes, it does not require complex rotary molds, offering greater flexibility in mold requirements and reducing supporting costs and debugging difficulty.

IV. Main Application Fields
High-End Home Furnishings: Imitation marble basins, imitation jade handles, artistic texture fruit baskets, etc.
Stationery & Educational Supplies: Color-mixed pen barrels, color-block office stationery, etc.
Beauty & Cosmetic Packaging: Artistic lipstick cases, high-end perfume caps, etc.
Auto Parts: Interior parts with special visual requirements.
V. Technical Considerations & Pitfall Avoidance Guide
Reject Rate Control: The core challenge of color mixing is stably producing aesthetic textures. The CMS system supports quick preset adjustment of mixing ratios, effectively reducing reject rates.
Color Change & Cleaning Optimization: The special structure of the color-mixing nozzle makes cleaning more difficult than standard nozzles. The model is optimized with a quick-disassembly structure to improve color change efficiency.
VI. Selection Tips
Mold Capacity & Tie Bar Spacing: Color mixing machines include dual injection units and mixing valve groups, occupying more space. Selection must not rely solely on clamping force—verify tie bar spacing matches mold dimensions.
Flexible Injection Volume Ratio: Supports differentiated configurations of primary and secondary injection units, enabling customized solutions like "large machine with small injection unit". For example, a 270-ton machine uses a large injection unit for the main color and a small one for accent colors, a core advantage of Konger.
VII. Tonnage Range & Core Models
Konger CMS standard models cover 140T–700T, balancing process stability and mainstream market demand.
Why Start at 140T?
Physical Space Limitation: The dual injection unit + color mixing valve group has a complex structure and cannot be compactly arranged in small-tonnage machines.
Mold Adaptation: Color mixing product molds are generally larger; the 410–460mm tie bar spacing of 140T models is the industry’s universal starting standard.
Why Cap at 700T?
Process Stability: Excessively large tonnage drastically increases melt volume, exponentially raising turbulence control difficulty and making uniform, attractive textures hard to guarantee.
Market Demand Coverage: 700T clamping force meets color mixing production for most high-end daily necessities, storage products, and furniture accessories.
Tonnage Quick Reference
CMS-140: Small daily necessities, high-end stationery, electronic cigarette housings
CMS-230/260: Star models, large cosmetic caps, two-color handles
CMS-320/400: Medium parts, imitation stone pattern basins, high-end fruit trays
CMS-500/700: Large color-mixed parts, imitation stone pattern stools, large storage boxes
Supplementary Note
While CMS standard models are capped at 700T, Konger provides fully customized solutions for customers with ultra-large product requirements (e.g., imitation stone pattern large table boards).
