Solving the problems of conventional injection molding, achieving high-level dimensional accuracy that was previously difficult!
Gas injection (gas-assisted molding) solves the issues of traditional injection molding and achieves high-level dimensional accuracy that was previously difficult. Instead of maintaining pressure after resin injection, high-pressure nitrogen gas is injected to maintain pressure from inside the product, which is also referred to as gas-assisted molding. With gas injection, it has become possible to significantly reduce the occurrence of defects such as sink marks, warping, and burrs that were common in traditional molding. Jun Corporation has adopted this gas injection technology early on and has established a high level of technical expertise that is among the best in the industry. We respond to our customers' strong trust across a wide range of fields, including automotive parts, housing equipment, and office appliances/electronics. We would like to introduce examples of improvements in gas injection (gas-assisted molding) by Jun Corporation. For more details, please contact us or refer to our catalog.

basic information
【Improvement Examples】 ◯ Cycle Shortening and Weight Reduction → Assist Grip → Clutch Pedal ○ Weight Reduction and Integration (Resinization of Pipes) → Achieved 70% weight reduction and 50% cost reduction by resinizing metal pipes ○ Reduction of Resin Usage → The short shot method does not require unnecessary resin ○ Solution for Hesitation Marks → Resolves the momentary stop of resin flow front! Controlled within 0.6 seconds of injection time ○ Design Reproduction → Even with thick walls, the design is preserved ○ Improvement of Appearance Quality → Resolves issues such as sink marks, warping, and burrs ○ Integration → Consolidates parts count into a single molding ○ Downgrading of Molding Machine → Molding can be achieved at about half the internal pressure due to gas pressure being significantly smaller than injection pressure ○ Improvement of Dimensional Accuracy → Enhances dimensional accuracy, including warping, ensuring consistent and safe production ○ Others: Jun Corporation's Capabilities (Elimination of Internal Foaming) → Eliminates internal foaming unique to gas injection! ○ Others: Jun Corporation's Capabilities (Consideration of Gas Injection Path) → We are particular about how gas is injected ● For more details, please contact us or refer to the catalog.
