Automatic Rotary Pulp Molding Machine
The ZONESUN ZS-PT1000 is an automatic rotary pulp molding machine for producing egg trays, fruit trays and other molded paper packaging with suitable molds. It uses vacuum suction to form prepared paper pulp into wet trays, with a production capacity of 800–1000 pcs/hour and a 3-mold configuration.
The machine serves as the core forming unit of a pulp molding production line. Optional pulping and drying systems support the process from recycled paper preparation to dried trays.

Machine Details
Rotary Continuous Forming
The rotary structure moves molds through pulp suction and dewatering stages in a continuous forming cycle.
Vacuum Suction Forming
Vacuum draws pulp fibers onto the mold surface to form the tray shape and remove water.
Wet Tray Transfer
Transfer molds move formed wet trays toward the downstream drying stage.
Quick-Change Molds
Replaceable molds allow different tray designs to be produced with suitable tooling.
Optional Pulping and Drying Systems
Upstream pulping equipment and downstream drying equipment can be configured around the forming unit.
Key Features and Benefits
- Rotary production: molds move through successive forming stages to support continuous tray production.
- Vacuum forming and dewatering: shapes pulp fibers on the mold and removes water before transfer.
- Replaceable tooling: suitable mold sets support different packaging shapes.
- Recycled paper processing: uses prepared pulp made from suitable recycled paper materials.
- Line configuration options: combine the forming unit with pulping and drying equipment for your production plan.
- Voltage options: 220 V and 380 V configurations are listed.
How a Pulp Molding Production Line Works
- Pulp preparation: upstream pulping equipment mixes suitable paper materials with water to prepare the slurry.
- Vacuum forming: the forming molds collect pulp fibers into the required tray shape.
- Dewatering: vacuum removes water from the formed pulp.
- Wet tray transfer: the formed trays leave the forming molds and move to the drying stage.
- Drying: a suitable downstream drying system removes remaining moisture.
- Finished tray handling: dried trays are collected for subsequent packing.
The ZS-PT1000 is the forming unit. Pulp preparation and final drying require the corresponding equipment; pulping and drying systems are optional line configurations.
How to Select Your Pulp Molding Setup
- Tray design: product drawings, dimensions, cavity layout and target finished weight.
- Raw material: available recycled paper types and intended pulp formulation.
- Output: required trays per hour and planned working hours.
- Drying: preferred drying arrangement and available energy supply.
- Factory conditions: available space, voltage, water supply and utility layout.
- Project scope: forming unit only or a line with pulping and drying equipment.
Frequently Asked Questions
What does the ZS-PT1000 produce?
It produces molded pulp trays and packaging, including egg trays and fruit trays, using molds matched to the required product design.
What is the production capacity?
The listed production capacity is 800–1000 pcs/hour.
Does the machine produce dry trays directly?
The forming process produces wet trays. A downstream drying stage is needed to obtain dried packaging.
Are the pulping and drying systems included?
They are listed as optional systems. The quotation should identify the equipment supplied for your selected line configuration.
Can one machine make different tray shapes?
The replaceable mold system supports different compatible designs. Each tray shape requires suitable forming and transfer tooling.
Can it use recycled paper?
Suitable recycled paper can be processed into pulp using upstream pulping equipment before feeding the forming unit.
Is every finished tray compostable?
Compostability depends on the fiber formulation, additives, coatings and applicable testing. The machine alone does not establish a finished packaging certification.
What information is needed for a quotation?
