Test Equipment


At Millwood Lab, we can test your products with many different pieces of equipment including our incline impact tester.Incline Impact Tester - The incline impact tester has a 2,000-pound capacity with an articulating sled. The sled can be used in the down position for package impacts into the back-stop. With the addition of a forktine assembly to the backstop, pallet designs are tested for impact resistance using the sled in the down position. With the sled in the horizontal position, full unit load systems can be tested for impact or stability.


Want to know how damaged your boxes can get without breaking? Let us test your product on our compression table.Compression Tester - The compression tester is hydraulic ram system with a maximum 50,000 pound load cell. The 60x60 inch platen can be operated as a fix platen system or used in conjunction with an airbag for a uniform load capacity. Various bottom fixtures can be incorporated to test pallets in any support configuration required. The platen can be positioned to test unit loads up to 85 inches tall.


We can also test your product with our vibration test table.Vibration Tester - The vibration tester is a Lansmont Model 10,000. The 60x60 inch table will handle up to 3,000 pound payloads. The computer controls will perform sine sweep or random vibration testing.
