ZHD Thermoforming Series Optimizes Highspeed Food Packaging Production

Zhejiang Wylong Machinery Co., Ltd.'s ZHD series of fully automatic forming machines is aimed at high-volume production of takeout food containers and industrial packaging. The line includes three models with forming areas ranging from 680 by 450 millimeters to 750 by 850 millimeters, each with a maximum forming depth of 120 millimeters, according to the manufacturer's specifications. The equipment is designed for processors seeking stable output and forming precision across common plastic sheet materials.

ZHD line targets high-volume packaging production

The ZHD-680/450, ZHD-750/650 and ZHD-750/850 machines are built for production of takeout meal containers and industrial packaging. The manufacturer says the series combines servo drive systems with high-precision forming processes and has supplied equipment to customers in more than 60 countries.

The machines are positioned for packaging operations that require consistent output across multiple product types, including food-service containers and other formed plastic items. The series is designed around automated forming, material handling and scrap management functions.

Materials and product applications

The ZHD series supports PP, PET, PVC, PS and PLA plastic sheet materials, according to the specifications. Product applications include trays, lids, fruit containers, flower pots and clamshell boxes.

The machines use ESTUN and TRIO servo drive systems, with stretch and compressed-air technology at the forming station to support forming accuracy. A built-in waste winding unit is designed to simplify production flow and scrap handling.

Model specifications

The three models share a maximum forming depth of 120 millimeters, while forming areas vary by model.

The manufacturer states that the combination of servo drives and forming-station air technology is intended to maintain dimensional accuracy across production runs. The waste winding unit is included as part of the machine's standard production flow.

Installation requirements

Before installation, the manufacturer specifies that the following infrastructure requirements should be met to support operation of the ZHD series:

• Power supply: Three-phase, four-wire industrial power.
• Compressed air: Output greater than 2.4 mm³/min, with pressure greater than 6 kgs.
• Cooling water system: Displacement greater than 1.5 m³/min, with water temperature controlled between 30° and 50°.

Support and commissioning

Zhejiang Wylong Machinery provides technical support for installation and commissioning, according to the company. Experienced technical teams conduct on-site installation and testing to help ensure the equipment is brought into operation after delivery.

The support process covers the startup phase and verification of production performance, the manufacturer states. This is intended to help packaging operations reach the intended production efficiency after the machines are installed.
