The WDS series digital display packaging box pressure testing machine can be mainly divided into five models: WDS-10, WDS-20, WDS-50, and WDS-100. This machine adopts advanced design concepts, has a beautiful appearance, easy operation, and 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. This WDS digital display packaging box pressure testing machine is mainly used for testing the conventional mechanical performance indicators of various paper boxes, cartons, and packaging boxes. The professionally designed automatic control and data acquisition system achieves fully digital adjustment of the data acquisition and control process. This equipment is suitable for manufacturing industries such as petrochemicals, fibers, rubber, ceramics, food, pharmaceutical packaging, geotextiles, films, wood, paper, as well as product quality supervision departments at all levels. It is also suitable for teaching demonstrations in colleges and universities.

2、 Host structure:

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、 Scope of application:

The WDS digital display packaging box pressure testing machine is 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、 Performance indicators:

WDS digital packaging box pressure testing machine for compression testing and stacking testing ISO12048 and ISO2234

This test is used to evaluate the ability of packaging boxes to withstand compression and protect their contents from compression. It can also be used as a stacking test to study the performance of the bottom layer of packaging boxes when stored in a warehouse.

The WDS digital packaging box pressure testing machine specimen is placed between two parallel metal plates of the pressure testing machine, and then loaded. If conducting an extrusion test, the loading will be stopped when the packaging box cannot withstand pressure or reaches the predetermined load value or displacement. If conducting stacking tests, stop loading when the predetermined load is applied for a predetermined time or when the packaging box is unable to withstand pressure.
