------From Principles to Purchasing: A Comprehensive Guide to Choosing Cost-Effective Equipment
Keywords: Plastic Pendulum Impact Tester
In industries such as plastics, rubber, and composite materials, the impact resistance of materials is one of the key indicators for measuring product quality. Whether it's automotive components, electronic housings, or packaging materials, rigorous impact testing is required to verify their reliability. The Plastic Pendulum Impact Tester is the core testing equipment in this field. This article provides a comprehensive reference for enterprises and quality inspectors, covering equipment principles, application scenarios, and purchasing guidelines.
1. Equipment Overview: Core Functions of the Plastic Pendulum Impact Tester
1.1 Definition and Working Principle
The Plastic Pendulum Impact Tester is a specialized instrument that measures the impact strength of materials by releasing a pendulum to strike a sample. Its core principles are:
The pendulum is released from a preset height, strikes the sample, and swings to the other side. The energy loss is used to calculate the material's impact toughness.
Test results are expressed in terms of impact strength (unit: kJ/m² or J/m), directly reflecting the material's fracture resistance.
1.2 Key Technical Parameters
Impact Energy Range: Common models cover 0.5J to 50J, suitable for materials of different thicknesses and hardness levels.
Pendulum Pre-lift Angle: Standard is 150°, with some devices supporting angle adjustment.
Testing Standards: Supports international standards such as ISO 179, ASTM D6110, and GB/T 1043.
Data Output: Automatically records impact energy, absorbed energy, impact speed, and other parameters, with support for data export and printing.
1.3 Application Fields
Plastic Products: Impact resistance testing of injection-molded parts such as PP, ABS, and PC.
Rubber Materials: Toughness evaluation of automotive seals and shock absorbers.
Composite Materials: Performance verification of glass fiber and carbon fiber-reinforced materials.
2. Equipment Usage: Operating Procedures and Precautions
2.1 Standard Operating Steps
Sample Preparation: Cut materials to standard dimensions (typically 80mm×10mm×4mm), ensuring the surface is free of scratches.
Equipment Calibration: Check the energy loss of the pendulum under no load (should be ≤1%) and adjust the base to ensure it is level.
Sample Installation: Secure the sample in a V-shaped or U-shaped fixture to avoid loosening.
Start Testing: Release the pendulum to strike the sample; the device automatically calculates and displays the impact strength.
Data Recording: Repeat the test 3 to 5 times and take the average as the final result.
2.2 Maintenance and Safety Precautions
Regular Maintenance: Lubricate the pendulum bearings quarterly and check for loose fasteners.
Environmental Requirements: The equipment should be used in a controlled environment of 23℃±2℃ and 50%±5% humidity.
Safety Measures: Operators must wear safety goggles during testing and stay clear of the pendulum's swing range.
3. Purchasing Guide: How to Choose Cost-Effective Equipment?
3.1 Define Requirements: Industry and Testing Standards
Industry Matching:
Automotive and aerospace industries: Prioritize high-precision models compliant with ASTM D6110.
Packaging material companies: Focus on ISO 179 standards and ensure repeatability error is ≤3%.
Sample Type: High-impact energy (≥15J) is required for hard plastics, while low-energy models are suitable for soft rubber.
