From April 21 to 24, 2026, the global plastics and rubber industry will gather in Shanghai as CHINAPLAS 2026 grandly opens at the National Exhibition and Convention Center (Hongqiao).As a leader in mold 3D printing, Shanghai ESU Laser Technology Co., Ltd. (ESU Laser) will make a high-profile appearance with its overall mold 3D printing solutions, ANRY hot runner systems and ESU-CRB rubber cold runner technology.Booth No.: [2.2G84]

At this exhibition, ESU Laser's mold solution portfolio will fully cover and directly address pain points in the rubber and plastic molding industry:

MPS Overall Solution:

Driving the Industrial Upgrade of Rubber & Plastic Molding

The market may not lack single equipment or material suppliers. Yet only ESU Laser, with its deep expertise in mold 3D printing and accumulation of more than 200,000 application cases, can truly provide customized "MPS Overall Solutions" for mold enterprises.We offer one-stop services covering "equipment – materials – processes – software – auxiliary machines – training", helping mold enterprises establish and operate their own 3D printing divisions.

As the core of the solution, the E3‑420 Metal 3D Printer is the third-generation product independently developed by ESU Laser. It features a golden build volume of 400×400×420 mm and can be customized with 2/4/6 lasers according to customers’ production capacity requirements. Paired with an optimized patented airflow system, it delivers higher precision, higher efficiency and higher stability.

Working in close synergy with it are our self-developed mold‑specific materials, such as EM400 high‑polishing mold steel and EM201 high‑thermal‑conductivity martensitic stainless steel, which have been granted invention patents in China and Europe, precisely meeting the stringent requirements of mold applications. More importantly, dedicated process packages including conformal cooling channels and ESU permeable steel, developed based on massive application experience, can shorten the molding cycle of rubber and plastic parts by up to 50%.

From equipment, materials and processes to printing services, additive‑subtractive manufacturing integration and turnkey plant setup, ESU Laser leverages this six‑in‑one deep coordination to provide rubber and plastic enterprises with a complete closed loop from mold design to efficient production, making 3D printing a core engine that truly drives industrial upgrading.

ESU-CRB Rubber Cold Runner Technology:

The Benchmark Manufacturing Process for Rubber Products

ESU-CRB Rubber Cold Runner Technology targets industry pain points in rubber injection molding, including severe raw material waste, frequent mold cleaning and maintenance, and premature vulcanization of rubber in the runner.By 3D-printing the cold runner body, it enables full conformal water channel wrapping around the rubber flow path, completely eliminating premature vulcanization (scorching) in the runner and solving the long-standing problems of waste and defective parts in elastomer molding.

This technology enables 100% recycling of runner rubber, greatly reduces the time spent on removing runner waste, realizes continuous automated production, and boosts product yield to 98%. It also cuts energy consumption by at least 30%, helping rubber products achieve green intelligent upgrading with "zero waste, high quality and high efficiency".

In addition, ESU Laser will also showcase 3D-printed mold inserts and ANRY hot runner systems, providing a complete mold solution matrix of "3D Printing + Hot Runner + Cold Runner". During the exhibition, the technical team will demonstrate the printing process on site, offer one-on-one consultations on rubber and plastic mold optimization, and share real cost‑reduction data from automotive, medical, packaging and other industries.

As the only national high‑tech enterprise in the market focused exclusively on mold 3D printing, ESU Laser has built a full 3D printing ecosystem covering "equipment, materials, processes, services, additive‑subtractive integration and turnkey plant setup". It has served more than 3,000 customers and accumulated over 200,000 application cases.

Its appearance at CHINAPLAS is not only a concentrated display of its full‑stack technical strength, but also an important practice of using additive manufacturing to drive the intelligent upgrading of the rubber and plastic industry!
