Growing Production in Peru with Inversiones Hercuplast SAC

In 2022, Inversiones Hercuplast SAC purchased two Chen Hsong MK6 Large machines, an 800T and a 1000T, to begin production in Peru. When the Chen Hsong team visited the factory in 2023, the facility had only recently been completed, with the first machines already in place and production getting started.

From Furniture to a Wider Product Range

When Inversiones Hercuplast SAC began production, its focus was on furniture. Since then, the company has expanded its range of plastic household products.
Today, its products include chairs, tables, trash bins, bathtubs and storage racks. As the product range grew, the company’s Chen Hsong machine lineup developed alongside it, with additional machines added over time.

Building a Broader Chen Hsong Machine Lineup

As Inversiones Hercuplast SAC expanded its production, its Chen Hsong machine lineup grew to include different machine series, each with its own strengths and applications.

MK6 Large: High-Speed Molding for Large Products

Inversiones Hercuplast SAC began production with an 800T and a 1000T MK6 Large.
The MK6 Large series is designed for high-speed molding and short cycle times, with a focus on consistent molding and lower energy consumption. At 1000T, the machine can achieve a dry cycle time of 4.5 seconds, while its repeatability accuracy error is less than ±0.25%.

For Hercuplast, the two MK6 Large machines formed the foundation of its production operation in Peru.

JM168-MK6 PRO: Precision Control for Demanding Applications

The JM168-MK6 PRO was later added to the company’s machine lineup as production developed.
The MK6 PRO combines responsive control with precise control of injection speed and pressure. Its closed-loop pressure control helps maintain consistent molding, making the series suitable for applications where dimensional stability and surface finish are important.
For manufacturers working with parts that require tighter control during molding, the MK6 PRO can be a suitable choice.

SM1700-TP-SMART: Handling Larger and More Complex Molds

The SM1700-TP-SMART became Hercuplast’s first two-platen machine.
The TP-SMART uses a two-platen design with a larger daylight and longer opening stroke, providing more room for larger and more complex molds. Its design also supports deep-cavity parts and molds with complex coring mechanisms.
For manufacturers working with larger or more complex molds, the TP-SMART offers a machine configuration suited to these requirements.

JM800-MK7S: Servo Technology with AI-Based Controls

In February 2026, Inversiones Hercuplast SAC purchased a JM800-MK7S, becoming the first customer in South America to have this model.
The JM800-MK7S belongs to the MK7S series, a precision servo injection molding machine with eDrive™. The MK7S combines high-response servo technology with intelligent controls, with a focus on repeatability, precision and flexible production.
As the latest addition to the factory, the JM800-MK7S further expands Hercuplast’s Chen Hsong machine lineup.

A Long-Term Partnership in Peru

For injection molding manufacturers, production requirements can change as product portfolios expand. Inversiones Hercuplast SAC’s development in Peru is one example of how a production operation can grow over time.

As its range of plastic household products expanded, additional Chen Hsong models joined the factory, including the JM168-MK6 PRO, SM1700-TP-SMART and JM800-MK7S.
Today, Inversiones Hercuplast SAC has a broader product range and a larger Chen Hsong machine lineup than when production began.

Chen Hsong is proud to continue supporting Inversiones Hercuplast SAC as its production operation develops in Peru.

FAQ

What type of injection molding machine is suitable for large plastic furniture?

The right machine depends on the product size, mold dimensions and required clamping force. For larger plastic products such as chairs and tables, higher-tonnage machines can provide the clamping force needed for larger molds. The MK6 Large series is designed for large molded products and covers clamping forces from 800T to 1650T.

How do I choose an injection molding machine for plastic household products?

Manufacturers should consider factors such as product size, mold dimensions, required clamping force, molding precision and production requirements. Different machine series offer different configurations, so the right choice depends on the specific application.

What is a two-platen injection molding machine used for?

Two-platen machines can be suitable for larger and more complex molds. The TP-SMART provides a larger daylight and longer opening stroke, making it suitable for applications involving larger molds, deep-cavity parts and complex coring mechanisms.

Which injection molding machine is suitable for parts with demanding dimensional requirements?

Parts with demanding dimensional requirements benefit from precise control of injection speed and pressure. The MK6 PRO uses closed-loop pressure control and is designed for applications where molding consistency and dimensional stability are important.

What injection molding machines does Inversiones Hercuplast SAC use?

Inversiones Hercuplast SAC’s Chen Hsong machine lineup includes an 800T and 1000T MK6 Large, a JM168-MK6 PRO, an SM1700-TP-SMART and a JM800-MK7S. The lineup covers different machine types and clamping forces as the company’s plastic household product range has expanded.
