This industrial plastic pallet welding machine joins molded PP, PE, or HDPE pallet sections with a controlled hot plate process. A large worktable supports heavy-duty, hygienic, storage, and logistics pallet designs, while servo-controlled movement and multi-zone temperature regulation help maintain alignment and a uniform weld around the pallet joint.
Production Benefits of Automated Plastic Pallet Hot Plate Welding
● Welding Objects: Modified PP, HDPE, PE, PET, and other plastics. Suitable for 1.5* 1.2m size pallet.Welded and formed through hot mold.
● Welding Medium: Heat welding, no additional medium required. Each module of the infraed plate features independent temperature control, utilizing a temperature module control system. Temperature adjustments and displays are fully managed via the human-machine interface.
● Equipment Capacity: Operates in 3 shifts per day, with each shift lasting 8 hours, allowing for continuous operation.
● Welding Cycle Time: 90 seconds per piece (excluding loading and unloading time) .
● Drive System: The equipment utilizes a servo/hydraulic system for operation.
Common Challenges in Plastic Pallet Manufacturing
Is manual assembly limiting output or creating uneven quality?
Do long weld paths make large HDPE or PP pallets difficult to align?
Are weak seams, warpage, or inconsistent cooling increasing rework?
Does each new pallet design require too much setup time?
Dizo Sonics develops the heater, fixtures, motion profile, cooling sequence, and changeover concept as one application-specific pallet welding solution.

Equipment Overview
This design removed the feeding tables, replace with two supporting tables. During the feeding, the pallets will be feed ed by workers manually. This way can speed up the feeding process. Lower the machine costs, but it will add extra labor work. This design can adapt to four collu ms pillar supporting system , this system can provide highly enchanced structure for the whole machine , make sure it can stands for high pressure from the servo system . 
Cost saving
In order to save some cost, little modification on 1600HM
1. Removed the seperated heating module, make it with one complete temperature control moduel.
2. The driven system uses hydraulic system. Save cost of removing the servo motor and servo control components.
3. Manual feeding, save cost of one fixture.(this model only has one fixture) 
Mexico Plastic Pallet Project:
Starting point: Eight manual lines producing approximately 500,000 pallets per year while facing delivery-pressure and quality variation.
Solution: Automated plastic pallet hot plate welding machines introduced in 2023.
Reported results:
- Daily output increased from 2,400 to 3,500 pallets, approximately 45%.
- Direct labor decreased from 24 to 9 operators.
- Product returns fell from 3.2% to 0.4%.
- Reported payback was eight months, followed by an order for two additional units.
Customer feedback emphasized stable equipment performance and timely remote after-sales support.
