Improvement case using gas injection (gas-assisted molding)

Improvement case using gas injection (gas-assisted molding)

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.

Example: [Plastic / Two-color molding] Sliding (Dissimilar material non-miscibility)

Example: [Plastic / Two-color molding] Sliding (Dissimilar material non-miscibility)

A combination of non-bonding dissimilar materials and incompatible resins! A good example that significantly reduced costs.

Our company is a manufacturer of plastic parts molding and processing. On this page, we will introduce a case study of our two-color molding technology, 'Sliding (Dissimilar Non-Miscible Materials).' This involves the integrated molding of the case and fins of a car air conditioning vent. Traditionally, fins of different sizes were assembled together, but with the combination of non-miscible resins that do not adhere, it has become possible to achieve integrated molding in two colors, leading to significant cost reductions. [Product Application Examples] ■ Car air conditioning vent - This method is also used in other applications, such as the joints of limbs in what is commonly known as Gundam plastic models. *For more details, please refer to the PDF document or feel free to contact us.

"Coating-free metallic resin molding" *Examples of applications by use are available.

"Coating-free metallic resin molding" *Examples of applications by use are available.

Eliminate the concept of "peeling" and extend the lifespan of products! Reduce manufacturing costs by eliminating the painting process! Examples include automotive parts and medical tube forceps.

Our company offers "Paintless Metallic Resin Molding," where we dye resin pellets in metallic colors and produce them through injection molding. Since there is no paint film, it does not become industrial waste and is recyclable. In the painting process, it is necessary to collect and dispose of the paint that is misted into the air, but this burden is eliminated. Additionally, the concept of peeling is removed, allowing us to eliminate processes such as overcoating, which reduces manufacturing costs due to the absence of painting processes. 【Features】 ■ Significant cost reduction achieved by eliminating the painting process ■ Elimination of the concept of "peeling," leading to longer product lifespan ■ Realization of resin reuse ■ Reduction of environmental impact *For more details, please refer to the PDF materials or feel free to contact us.
