In the injection molding industry, efficiency and cost are eternal themes. Faced with increasingly stringent environmental requirements and profit pressures, traditional production methods are no longer sufficient. Today, we will delve into the difference between ordinary injection molding machines and Unom non drying exhaust injection molding machines?
Three major pain points of ordinary injection molding machines

01
Drying process, cost black hole
Features:must be equipped
dryerYes, that's right
PAThe
PEEK、 ABS and other raw materials are pre dried for 2-12 hours.
Disadvantages:High equipment, electricity, labor, and site costs; If not dried properly, bubbles will form, and if baked excessively, the material will become brittle and turn yellow.
02
Quality defects, difficult to control yield
Features:The moisture in the raw materials forms an "air cushion" inside the barrel, causing the screw to slip.
Disadvantages:The surface of the product frequently shows bubbles, silver lines (material patterns), and burning, and the stability is extremely poor during low-speed glue injection (there is a "low-speed dead zone"). The high appearance requirements result in a low product qualification rate.
03
The processing of recycled materials is difficult and the process is cumbersome
Features:The moisture content of recycled materials fluctuates greatly, and traditional machines cannot directly process them.
Disadvantages: It is necessary to first pelletize and then dry, which results in a long process, high cost, and significant performance degradation.
Six disruptive advantages
Unom is not simply an improvement, but a reconstruction of the production process through active exhaust technology, directly outputting "results" for you.
One step delivery, ready to use for feeding
The original active exhaust system uses an ultra long diameter ratio screw (23:1) for high-temperature extrusion and stirring, actively discharging moisture and volatile substances from the raw materials. Whether it is high moisture absorbing new materials or recycled materials with unstable moisture content, they can be directly put into production without drying or pre granulation, eliminating the need for the entire pre-treatment process.
Shooting speed up to 300mm/s, no low-speed dead zone
When the traditional firing rate is below 10mm/s, the screw cannot crawl; Accuracy drops sharply when it exceeds 150mm/s. And Yoonom achieves precise and controllable shooting speed of 0-300mm/s throughout the entire range, stable from extremely low speed to high speed, especially suitable for high-precision products such as light guide strips and thin-walled parts.
Active exhaust, soaring accuracy
Due to the complete elimination of water vapor, there is no "air cushion" interference inside the melt. The screw drives the plastic without delay or slippage, with instructions and actions completely synchronized, achieving a high injection termination accuracy of ± 1mm and significantly improving the yield rate.
Low temperature molding, energy-saving protection
The processing temperature is 10-30 ℃ lower than traditional machines. This means shorter cooling time (15% -30% reduction in cycle time), lower heating electricity costs, and perfect protection of thermosensitive materials (biodegradable materials, flame retardants, etc.) from degradation and corrosion of molds.
The product has stronger performance and better appearance
Eliminate defects such as bubbles, silver lines, floating fibers, and whitening from the root. Excellent secondary mixing ability results in excellent dispersion of colorants, denser product structure, superior mechanical properties, and a top-notch appearance.
Safe and environmentally friendly, cleaner workshop
No dryer heat source, no dust, no noise, lower workshop temperature, completely eliminating fire hazards and occupational health risks.
