DKM Full Electric Machine Production Line -Energy-saving, high-efficiency, precise control, high-speed response
The 38th China International Exhibition on Plastics and Rubber Industries (CHINAPLAS 2026) will be grandly held at the National Exhibition and Convention Center (Hongqiao), Shanghai from April 21 to 24, 2026.DKM Injection Molding Machine will present its colorful water cup production line — a highlight of its latest all-electric machine series — at Booths 5.1C71 & 5.1C75.The colorful water cup changes color with viewing angles without the use of color pigments, achieved through a special process, combining attractive appearance and practicality.
The colorful water cup is a precise collaboration of light and structure. Based on the principle of light interference and reflection, its dazzling colors are achieved through laser-engraved nanostructures without any added pigments, combining practicality and aesthetic appeal.
Light Interference and Reflection
The dazzling color effect relies on the principle of light interference and reflection. When natural light strikes the special structure of the cup body, light waves split and superimpose to produce various colors without additional dyes.
Core Principle
Nanoscale Precision Structure
The core process involves creating microstructures or layered film structures on the mold surface, which are then replicated onto the cup body via injection molding.
The critical step uses high-precision laser to engrave nanoscale gratings or grooves on the mold surface, precisely controlling light propagation to enhance the color-shifting effect, requiring extremely high accuracy.
Key Process
The iridescent effect mainly depends on three factors: viewing angle, distance from the light source, and light source brightness. Changes in these aspects will alter the hue and saturation accordingly.
Factors Affecting Visual Appearance
Full electric injection molding machines offer distinct advantages in energy saving, efficiency, precision, clean production, maintenance cost and environmental protection.They provide customers with precise, stable and intelligent high-efficiency production solutions, making them an ideal choice for modern manufacturing to transform toward intelligence and green development.All-electric injection molding machines are easy to automate and intellectualize, aligning with the development trend of Industry 4.0.They help realize unmanned “lights-out factories”, improving production efficiency and flexibility.With technological advancements and cost reduction, all-electric injection molding machines enjoy broad market application prospects.
High energy utilization rate: The all-electric injection molding machine is directly driven by servo motors, with an energy conversion efficiency of over 95%, which is much higher than the 30-50% of traditional hydraulic systems.
No hydraulic oil required: The all-electric injection molding machine does not use hydraulic oil, reducing the costs of purchasing, maintaining and disposing of hydraulic oil, and also avoiding environmental pollution caused by hydraulic oil leakage.
Energy efficient
High positioning accuracy: The servo motor and precision control system of the all-electric injection molding machine can achieve positioning accuracy of 0.01mm to ensure the accuracy and consistency of the injection molding products.
Stability: The whole production process via the all-electric machine will not be affected by oil temperature changes. Its stable injection performance can ensure high quality of the products.
Precise control
Fast response: The servo motor has a fast response time of 10 ms, which is significantly quicker than the hydraulic system’s response time of 100 ms. This faster response greatly shortens the molding cycle and enhances production efficiency.
Fast response
