Accurate Thermal Systems ATS1041 Cooling Rack and Sieve Assembly

Overview

The Accurate Thermal Systems ATS1041 Cooling Rack and Sieve Assembly is an engineered auxiliary workstation designed specifically for post-processing handling of hot tooling components in polymer processing laboratories and production environments. It operates on a dual-function mechanical principle: passive convective cooling of heated parts—such as extrusion dies, injection molds, and nozzle assemblies—combined with gravity-assisted particulate separation via a precision-fitted stainless steel sieve. The assembly does not incorporate active thermal management (e.g., forced air or liquid cooling), but instead leverages ambient airflow and thermal mass dissipation to reduce surface temperatures safely below 60 °C within typical handling timeframes (15–25 minutes, depending on part mass and initial temperature). Its primary engineering objective is to mitigate thermal hazards during manual cleaning operations while enabling closed-loop recovery of abrasive media—particularly fused alumina sand—used in thermal cleaning ovens and burn-off systems.

Key Features

• Robust welded steel frame with high-temperature powder-coated finish (rated to 200 °C continuous exposure) for structural integrity and corrosion resistance.
• Removable 12-mesh (1.68 mm aperture) stainless steel sieve tray, laser-cut for uniform open area and edge durability; compatible with standard alumina sand grain sizes (20–60 mesh).
• Ergonomic height and footprint optimized for integration beside thermal cleaning ovens (e.g., ATS Series burn-off units), minimizing operator reach and lift effort.
• Integrated collection pan with 1/4″ lip and non-slip rubber feet ensures containment of recovered abrasive media and prevents spillage during transport.
• No electrical or pneumatic connections required—fully passive, maintenance-free operation compliant with Class I, Division 2 hazardous location guidelines where applicable.

Sample Compatibility & Compliance

The ATS1041 accommodates tooling components up to 19″ × 18″ in plan view and ≤ 4″ in vertical stack height when placed on the sieve surface. It is routinely deployed in labs conducting ASTM D5213 (standard practice for thermal cleaning of plastic processing equipment) and ISO 11357-5 (plastics—differential scanning calorimetry—part 5: determination of thermal degradation behavior). While the unit itself carries no CE or UL certification as a standalone device, its materials and construction conform to OSHA 1910.132 (personal protective equipment standards) and ANSI Z535.4 (product safety signs) requirements for industrial auxiliary equipment. All hardware meets RoHS 2011/65/EU material restrictions.

Software & Data Management

This is a purely mechanical, non-instrumented accessory—no embedded sensors, firmware, or connectivity interfaces are present. Consequently, it generates no digital output or telemetry. However, it integrates seamlessly into documented laboratory workflows governed by GLP and GMP frameworks: its use is commonly recorded in equipment logbooks, thermal cleaning SOPs (e.g., SOP-TC-07), and material recovery tracking sheets. When used in FDA-regulated facilities, the ATS1041 supports Part 11-compliant documentation practices through traceable batch records indicating abrasive media reuse cycles and visual inspection timestamps.

Applications

• Post-burn-off cooling and residue capture for extrusion dies, manifold blocks, and hot-runner systems prior to ultrasonic or mechanical cleaning.
• Controlled cooldown staging for injection mold inserts undergoing alumina sand blasting or thermal cycling validation studies.
• Recovery and sieving of reusable fused alumina abrasive media (typically 95–99% Al₂O₃, Mohs hardness ≥ 9) following thermal descaling cycles.
• Reduction of airborne carbonaceous particulates during tooling cleanup—contributing to facility-wide ISO 14644-1 Class 8 cleanroom compliance in adjacent lab zones.
• Supporting sustainability initiatives by extending abrasive media service life beyond 12 thermal cycles (per internal ATS validation data under controlled humidity conditions).

FAQ

Is the ATS1041 compatible with non-alumina abrasives such as silicon carbide or ceramic beads?
Yes—provided particle size distribution falls within the 10–40 mesh range and bulk density remains below 2.2 g/cm³. Sieve retention efficiency drops above 45 mesh due to reduced gravitational throughput.
Can the sieve be replaced with custom mesh counts?
Yes. Accurate Thermal Systems offers optional 8-mesh (2.38 mm) and 16-mesh (1.19 mm) stainless steel trays under part numbers ATS-SV-08 and ATS-SV-16, respectively.
Does the unit require anchoring or floor mounting?
No—it is freestanding and stable under normal handling loads. Anchoring is only recommended if deployed in seismic Zone 4 or near high-vibration machinery.
What is the expected service life of the standard sieve under daily use?
Minimum 18 months at two thermal cycles per day, assuming proper handling (no impact loading or chemical immersion) and periodic visual inspection for wire deformation.
Is technical support available for integration with automated thermal cleaning lines?
Yes—ATS provides mechanical interface drawings (PDF and STEP formats) and dimensional tolerance guidance for robotic end-effector integration or conveyor-fed staging configurations.
