Advancing competitiveness with Super-Foam Technology

Woojin Plaimm is fortifying its global presence by leveraging its innovative 'Super-Foam' and 'Clean-Foam' technologies. These advancements, co-developed in collaboration with the company's Austrian R&D Center, highlight the company's commitment to integrating Korean manufacturing expertise with European technological innovation to expand its market footprint.

The Austrian R&D Center plays a pivotal role in enhancing the quality and technological capabilities of Woojin Plaimm's injection molding machines. By combining the Austrian team's innovative technologies with the production capabilities of the Korean headquarters, Woojin Plaimm continues to deliver cutting-edge solutions tailored to diverse global demands.

Richard Wagner, Head of the Control Research Team at the Austrian R&D Center, emphasizes the importance of this synergy, stating, "Our efforts are centered on developing efficient control systems and improving drive and hydraulic technologies. This collaborative approach ensures that we meet the dynamic needs of customers worldwide."

'Super-Foam' Technology: Advancing efficiency and sustainability

Woojin Plaimm's 'Super-Foam' technology represents a breakthrough in low-pressure physical micro-foaming injection molding. This technique dissolves inert gas into molten resin under low pressure (below 10 MPa) before injecting it into molds, offering several benefits: quality enhancement as it prevents shrinkage and deformation, significantly improving product quality; weight reduction of up to 60% compared to solid injection molding; cost savings due to reduced raw material consumption; productivity improvement as it eliminates the need for pressure-holding processes, shortening cycle times; operates at lower processing temperatures, contributing to energy conservation; and durability as well as versatility as it works with a wide range of materials without requiring specialized foaming resins.

These benefits, coupled with the global push for carbon neutrality, make 'Super-Foam' a transformative solution for industries like automotive, where lightweight and durable components are critical for the growing electric vehicle market.

'Clean-Foam' Technology: Beyond limitations — no sink, clean surface

'Clean-Foam' technology builds upon the innovations of 'Super-Foam,' utilizing a unique molding process where the skin layer is made of virgin material while the core layer consists of either virgin or recycled materials.

This approach employs Woojin Plaimm's proprietary foaming techniques, resulting in: the elimination of sink marks entirely, ensuring a clean, smooth surface; absence of surface defects allows for immediate painting after injection molding; and successfully addressing the limitations of traditional physical foaming, such as surface defects and sink marks.

The 'Clean-Foam' process is a game-changer, enabling high-quality production with a focus on sustainability and efficiency.
