Additional information

RT-310 Thermal shock impact testing chamber

Thermal shock impact testing chamber(2 boxes) used to test the change of material under extremely high temperature and extremely low temperature environment that continue alternation in the shortest time, testing the chemical changes or physical damage of material caused by the thermal expansion and contraction.

Product Overview

The KR‑310 two‑zone thermal shock test chamber is vertical‑shuttle‑type environmental reliability equipment. It features independent high‑temperature pre‑heat zone and low‑temperature pre‑cool zone. Test specimens are placed inside a pneumatically‑driven shuttle basket, which swiftly shuttles between hot and cold zones. It subjects DUTs to rapid extreme‑temperature alternation, simulating severe thermal‑expansion‑and‑contraction stress in real‑world application scenarios.

Engineers inspect physical deformation, cracking, delamination and chemical property changes after repeated hot‑cold shocks. This floor‑standing unit serves reliability validation for semiconductors, IC chips, PCB assemblies, automotive electronics, aerospace components, rubber‑plastic parts and metal hardware. It supports product R‑D screening, incoming‑batch QC and standard‑compliant certification testing according to military and civilian environmental‑test specifications.

Core Product Competitive Advantages

Independent dual‑thermal‑storage‑zone shuttle‑type architecture
Separate high‑temperature chamber and low‑temperature chamber maintain preset thermal conditions continuously. Only the sample‑carrying basket moves vertically via cylinder drive; zone temperatures stay stable without repeated heating‑cooling cycles, shortening test turnaround and improving energy‑efficiency. Basket transfer time is controlled within ≤10 seconds. Post‑switch temperature recovery finishes within 5 minutes under no‑load status.
Balanced Temperature Control (BTC) + multi‑loop PID regulation
Adopts BTC balanced temperature‑control logic paired with SSSR proportional output. The system dynamically matches heating output against real‑time heat loss, securing stable long‑duration cyclic‑shock running without frequent overshooting or temperature drift. Temperature fluctuation reaches ±0.5 ℃ and temperature uniformity ±2.0 ℃ across zones.
Full‑featured true‑color PLC touch‑screen HMI
7‑inch 800×480 true‑color touch panel supports Chinese‑English toggle. It stores up to 127 groups of multi‑segment test profiles, each segment configurable up to 530 h 59 min, with maximum 32 000 repeat‑cycle execution. Real‑time curve plotting, fault self‑diagnosis with troubleshooting hints, USB‑disk data‑export and RS232/RS485 remote‑communication are built‑in. Power‑off resume modes (hot‑start / cold‑start / stop) and scheduled power‑on functions are available for unattended testing.
High‑performance imported refrigeration assembly
Equipped with Bitzer semi‑hermetic or Copeland fully‑hermetic compressors. Environment‑friendly R404A / R23 refrigerants are deployed. The refrigeration loop applies nitrogen‑shielded welding and vacuum pumping craft. Auto‑adjusting energy‑regulation evaporator adapts variable‑load conditions and reduces frosting risk under long‑time operation. Imported expansion‑valve, oil‑separator and drying‑filter guarantee refrigeration‑circuit dependability.
Robust cabinet construction & comprehensive multi‑layer safety interlocks
Inner cavity uses SUS304 stainless‑steel sheet. High‑temperature section adopts 24K glass‑wool insulation; low‑temperature section combines PU foam plus glass‑wool composite insulation material. A Φ50 mm reserved test port with silicone plug allows powered‑on sample‑wiring. Complete protective mechanisms include heater dry‑burn‑protection, fan‑overload, compressor high‑pressure / over‑heat / phase‑sequence‑error protection and circuit‑breaker safeguards. Mobile casters plus levelling feet facilitate on‑site positioning.

Standard Complete Test Operating Workflow

Pre‑Test Preparation

Place unit on level well‑ventilated floor. Supply qualified ≥0.6 MPa compressed‑air source. Inspect refrigeration system, pneumatic‑cylinder shuttle‑basket, circulating‑fan and full safety‑alarm functions. Mount test‑pieces onto stainless‑steel sample trays; keep proper clearance between specimens for full‑airflow exposure. Close all chamber doors securely. Switch‑on main‑power.
Program Configuration

On touch‑screen HMI, create or recall saved multi‑segment thermal‑shock profile: define hot‑zone temperature, cold‑zone temperature, dwell‑time for each zone and total shock‑cycle quantity. Select power‑off‑resume logic and enable data‑logging function. Start pre‑heating / pre‑cooling; wait for hot‑cold zones to stabilise at target set‑points.
Execute Hot‑Cold Thermal‑Shock Test

Launch test sequence. Pneumatic cylinder drives sample basket to shuttle back‑and‑forth between high‑temperature and low‑temperature zones automatically. System records temperature curves and running‑history continuously. The chamber stops automatically once completing preset total‑cycle count.
Specimen Retrieval & Performance Assessment

After program termination, wait until sample basket temperature rises close to ambient range before opening doors. Take‑out DUTs. Inspect for cracks, coating‑peeling, solder‑joint‑failure, deformation and other thermally‑induced defects. Document observations for QC‑reports. Multiple replicate‑specimen tests are recommended for statistically‑valid conclusions.
Post‑Test Tidying

Clear dust and debris inside test‑basket and cavity. Export stored test data via USB‑disk if needed. Reset program‑parameters. Shut‑down main‑power for long‑term idle storage. Periodically check refrigeration‑circuit status, door‑seal gaskets and pneumatic‑system tightness.

Safety‑Operation‑Reminder

Do not open chamber doors while inner zones stay at extreme high / low temperature, to avoid scald or frost‑bite hazard. Stable ≥0.6 MPa dry‑clean compressed‑air supply is mandatory for shuttle‑basket movement. Reliable three‑phase power‑grounding must be completed before power‑on. Do not frequently power‑cycle the machine in short intervals to protect compressor service‑life. Periodically inspect pneumatic‑pipeline and door‑gasket sealing performance.
