SCT-PLC

PLC-Controlled Stress Crack Tester

The SCT-PLC Stress Crack Tester determines PET bottle base stress crack resistance with PLC control for high accuracy, two test modes (SP and PS), and multi-position design. Accommodates 60-120mm diameter, 150-350mm height samples with testing times up to 200 minutes.

PLC-Controlled Stress Crack Tester

The AT2E SCT-PLC Stress Crack Tester is designed to test the internal stress in a bottle base and determine the stress crack resistance of blow-moulded PET carbonated soft drink bottles, by measuring the propensity for base cracking upon exposure to an aqueous sodium hydroxide solution under a controlled environment — estimating the long-term behaviour of bottles.

Key Features

  • Multi-position design for convenient, efficient testing.
  • Two test modes: “SP” (fill samples with water, fill vessels with solution, then lower and pressurise per cycle setting) and “PS” (pressurise the sample first, hold, then lower and continue pressurising per cycle setting).
  • PLC control ensures high accuracy and reliability.
  • High-quality stainless steel frame — safe and durable.
  • Flexible position selection — each position controlled separately by the system.
  • Anti-explosion, clear observation window for safe viewing during tests.
  • Testing time selectable from 0 to 200 minutes (consult AT2E for longer testing time requests).

Applications

Ideal for PET bottle manufacturers requiring accurate, repeatable, PLC-controlled stress crack testing to verify base durability ahead of production.
