Plastic Pallet Blow Molding Machine

A plastic pallet blow molding machine may be advertised at around US$160,000–320,000, depending on its configuration, production capacity, and automation level. However, this is an indicative range from public supplier listings, not a verified global transaction price. Before comparing quotations, confirm whether the price includes the pallet mold, auxiliary equipment, automatic trimming, installation, commissioning, and shipping. Request separate prices for the machine and mold so you can calculate the actual investment required to start production.

Actual production output depends on pallet weight, extrusion or accumulation time, cooling, demolding, trimming, and rejected parts. A machine advertised with a dry-cycle speed of 120 cycles per hour does not mean it will produce 120 finished pallets per hour, because dry cycling does not represent the complete molding process. To estimate production, use the formula: good pallets per hour = 3,600 ÷ actual cycle time in seconds × good-part rate. For example, a 120-second cycle theoretically allows 30 cycles per hour; at a 95% good-part rate, output is approximately 28.5 accepted pallets per hour. Ask suppliers to verify cycle time and good-part rate using your actual pallet mold and material rather than relying on headline specifications.

Blow molding is generally worth evaluating for hollow, double-wall pallet designs, while injection molding is commonly used for solid-wall or rib-reinforced pallet structures. The better option depends on pallet geometry, target weight, required static and dynamic loads, tooling investment, production volume, and acceptable cycle time. Do not compare the processes using machine price alone: request quotations for the complete machine, mold, auxiliary equipment, and estimated operating costs for the same pallet specification. Ask both suppliers to produce or validate a sample and compare pallet weight, dimensions, load-test results, cycle time, and labor requirements. This side-by-side comparison provides a more reliable decision than assuming one process is always cheaper or more productive.

Some blow molding systems can process suitable recycled HDPE, but performance depends on the material's melt flow properties, contamination, moisture, additives, and batch consistency. Do not assume that all recycled HDPE is suitable simply because the machine is designed for HDPE. Ask the supplier to test your intended recycled-material grade and blend ratio, then evaluate extrusion stability, wall-thickness distribution, surface defects, cycle time, and finished-pallet load performance. If recycled material is part of your cost-saving plan, include the test results in the purchase acceptance criteria.

A single machine may produce different pallet designs if its clamping force, mold space, shot capacity, and plasticizing output meet the requirements of each product. However, a heavier pallet generally requires more material per shot and may increase cooling time, so the same machine will not necessarily achieve the same output rate across all designs. Provide the supplier with the target pallet weight, dimensions, material grade, and required static, dynamic, and racking loads, then request a model-specific feasibility assessment and production trial before confirming the order.
