At TaipeiPLAS 2026, Huarong will focus its four showcased technologies on four common challenges faced in manufacturing：

     1. How to reduce product weight and material usage

     2. How to enable different materials to perform their respective functions within the same product

     3. How to improve the operation and automation conditions of large vertical injection molding machines

     4. How to bring quality inspection closer to the actual injection molding cycle

These four exhibits address materials, processes, equipment design, and quality control respectively, demonstrating Huarong’s development direction from injection molding machines to comprehensive process solutions.

HRF-200 Microcellular Foaming Injection Molding

Huarong will showcase the HRF-200 Microcellular Foaming Injection Molding Machine, which uses supercritical fluid technology. Nitrogen or carbon dioxide can be used according to process requirements to form a microcellular structure within the molten plastic.

Based on current technical data and different product conditions, the microcellular foaming process can be evaluated toward approximately 15% to 20% product weight reduction, 10% to 20% material savings, and approximately 30% to 50% reduction in required clamping force; under specific application conditions, cases with higher weight reduction ratios have also been achieved. Actual results still depend on product structure, material, mold, and process conditions.

HRM-200 Sandwich Injection Molding

The HRM-200 Sandwich Injection Molding Machine exhibited at the show can form a material-layered structure of outer layer → core layer → outer layer (Skin/Core/Skin) within a single injection molding cycle.

The outer layer can focus on product appearance, color, or specific surface properties, while the core layer can be evaluated for recycled materials, functional materials, reinforcing materials, or foamed materials according to product requirements, allowing product design to no longer be limited to using the same material from the surface to the interior.

This technology enables manufacturers to further consider material configuration from a product-structure perspective, creating greater design flexibility among appearance, performance, material cost, and sustainable applications.

From Material Reduction to Multi-Material Design：Rethinking Plastic Product Strategies

Material efficiency is not simply about “reducing plastic usage,” nor is it simply about switching to recycled materials.

Once a product enters the development and mass-production stages, product weight, surface quality, mechanical properties, material flowability, mold design, and cost all interact with one another. Therefore, manufacturers need different technology pathways that can be selected according to product conditions.

HRF microcellular foaming and HRM sandwich injection molding represent two different material strategies. The former reduces the proportion of solid material inside the product through the molding process, while the latter reconfigures the position of different materials within the product cross-section.

HRF Microcellular Foaming：Lightweighting While Maintaining Dimensional Stability and Process Conditions

Microcellular foaming is suitable for evaluating applications in certain automotive components, electronic products, sporting goods, transportation products, and industrial plastic parts. PP, PC/ABS, PA, glass-fiber-reinforced materials, and PCR recycled materials can all be further evaluated according to appearance, strength, and actual process conditions.

However, microcellular foaming is not suitable for every product. Product appearance requirements, transparency requirements, structural strength, material properties, and mold conditions all directly affect final feasibility. Therefore, at the exhibition, in addition to demonstrating the equipment, Huarong will also discuss application conditions and limitations based on customers’ actual products, rather than simply using weight reduction ratios as the sole criterion for equipment evaluation.

HRM Sandwich Injection Molding: Material Configuration Must Return to the Product and Mold

The key to sandwich injection molding is not simply having two injection units.

Material compatibility, viscosity, product wall thickness, gate location, mold design, flow balance, and the switching timing between Skin and Core materials all affect the final material distribution and product quality.

Therefore, the true engineering value of sandwich injection molding is to enable product developers to think separately about “what the outer layer needs” and “what the core layer needs” at the initial stage of product development, and then determine the final solution through the integration of materials, molds, and injection molding processes.

Low-Platform Vertical Injection Molding Machine：Extending Equipment Performance to the Actual Operating Environment

Vertical injection molding machines are widely used for terminals, wires, connectors, electronic components, and metal insert applications such as insert injection molding.

As mold sizes and machine tonnage increase, the operating platform height may also increase accordingly. In actual production, this is not merely a matter of whether it is convenient for operators to get on and off the equipment; it can also directly affect the configuration of insert feeding, robotic arms, conveyors, and automated workstations.

Therefore, Huarong will use this exhibition to rethink the mechanical structure and production-line configuration of large vertical injection molding equipment from the perspective of working height.

Low-Platform Design Makes Insert Placement and Automation Integration More Direct

The Low-Platform Vertical Injection Molding Machine exhibited this time is designed to reduce the working height of large vertical injection molding machines, allowing operators to more easily access the actual molding area when placing terminals, wires, metal inserts, and removing molded products.

For manual operations, this can reduce the operational complexity caused by frequent climbing onto elevated platforms; for automation planning, the lower working position can also facilitate the configuration of robotic arms, insert feeding systems, and other peripheral equipment.

Through this design, Huarong aims to ensure that the development of large vertical injection molding machines focuses not only on clamping force, injection capability, and mold space, but also incorporates operator ergonomics and future automation integration into the equipment design requirements.
