The WDW microcomputer controlled packaging box pressure testing machine can be divided into several models: WDW-10, WDW-20, WDW-50, and WDW-100. The machine adopts advanced design concepts, with beautiful appearance, easy operation, stable and reliable performance. The computer uses the fully digital control system (PCI card) developed by our company, directly controls the servo speed control system and servo motor rotation. The speed of the AC servo motor is reduced by the deceleration system and transmitted to the precision ball screw pair to achieve actions such as raising, lowering, and testing of the crossbeam, completing mechanical performance tests such as tensile and compressive testing of the sample. This testing machine meets the requirements of GB/T16491-2008 "Electronic Universal Testing Machines" and JJG-1986 "Verification Regulations for Electronic Universal Testing Machines"; Scope of use: The testing requirements for cardboard boxes in the SN/T0262-93 "Inspection Regulations for Corrugated Paper Boxes in Export Commodity Transport Packaging" GB/T4857.4-92 "Pressure Test Methods for Packaging and Transport Packages" standard.

2、 The host adopts:

1. Portal frame structure, spray painted casing, clean and elegant appearance.

2. The screw only bears tensile force, effectively extending its lifespan and rigidity stability

3. Ball screw pair loading method, double nut back tightening to eliminate clearance, ensuring high rigidity and high dynamic performance of the system

3、 Product Usage:

Suitable for compression and holding tests of various packaging bodies and cartons, the test results can serve as an important reference for the height of finished packaging boxes stacked in factories or an important basis for designing packaging boxes. Ideal testing and research equipment for packaging and printing enterprises, factories and mines, technical supervision departments, inspection agencies, research institutes, and colleges and universities. Various packaging container pressure tests, deformation tests, and stacking tests can be conducted according to domestic and foreign standards such as GB/T485.4-2008, ASTM D642, D4169, ISO2872, JIS Z0212, etc.

4、 Product performance:

1. Strength test: can measure the maximum compressive strength and displacement of the box body;

2. Fixed value test: The overall performance of the box can be tested based on the set pressure or displacement;

3. Stacking test: Stacking tests can be conducted at different times, under different conditions, and with different force values according to national or international standards.

Professional software can automatically calculate data and indicators such as elastic modulus, yield strength, compressive strength, fracture strength, specimen elongation, stiffness of the shock absorption system, deformation under constant force, and force under constant deformation. It can meet the closed-loop control mode of constant displacement, constant stress, and constant deformation, and the testing process can be programmed and controlled according to standard requirements. The control and data processing of the experimental process by the computer control system comply with the requirements of the corresponding national standards for metallic and non-metallic materials, and the test reports are diversified in various ways such as WORD, EXECEL, etc.
