Product Overview

The KR‑855A compact lab‑grade stenter‑setting system integrates a high‑temperature steaming‑drying cabinet and a standalone electric steam generator. It is developed for dyeing‑finishing laboratories to simulate real‑factory production‑scale heat‑treatment workflows. The equipment executes diversified sample‑processing tasks, including steam ageing, resin‑curing baking, thermal‑fixing and hot‑air drying of fabric specimens.

By reproducing actual manufacturing thermal‑moisture conditions, technicians can screen dye‑formula schemes, assess color‑shift risks during finishing procedures and validate textile‑chemical auxiliary effects. It also supports the preparation of tactile reference‑samples and color‑comparison swatches for R‑D and quality‑control work. Woven fabrics, knitted textiles and blended fibre‑samples can be tension‑controlled in both warp and weft directions on dual‑direction pin‑plate frames.

Core Product Competitive Advantages

1. Modular Dual‑Unit Configuration: Oven plus Separate Steam‑Boiler The system consists of two independent assemblies: high‑temperature steam‑drying oven and dedicated steam‑generator. Operators can run pure electric‑heating drying or combined steam‑and‑electric‑heating procedures. Separate steam source delivers stable saturated steam, avoiding moisture‑supply fluctuation that would impact sample‑processing consistency.
2. Full SUS304 Anti‑Corrosion Stainless‑Steel Main‑Structure All chambers, internal runners and fluid‑contact components adopt SUS304 stainless‑steel material. It resists corrosion from textile auxiliaries, steam and high‑temperature‑humidity atmosphere, extending equipment service‑life in humid dye‑lab surroundings.
3. Precision‑Controlled Dual‑Direction Pin‑Plate Stenter Frame Two‑set pin‑plate assemblies support warp‑weft bidirectional stretching. Tension parameters are freely adjustable to fit woven and knitted‑textile samples. Specimens are fixed without slippage during heating‑steaming cycles to faithfully reproduce industrial stenter‑machine tension‑setting conditions.
4. Automated Feeding‑Discharging with Programmable Timing & Reminder Alarm High‑temperature‑resistant imported motor‑driven chain‑transport mechanism completes automatic sample feeding into chamber. Users set holding duration from 1‑99 minutes. Upon completion of preset runtime, samples are ejected automatically and audible alarm is triggered, reducing manual‑supervision workload.
5. Circulating‑Hot‑Air System with Multi‑Mode Temperature‑Steam Combination Circulating‑hot‑air design ensures uniform heat distribution across the whole processing cavity. Three‑processing‑modes are available: normal electric‑heating drying; saturated‑steam baking (102 °C ±2 °C); composite steam‑electric‑high‑temp treatment covering 100‑250 °C. Built‑in cooling‑fan speeds up chamber cooling between test‑batches.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Inspect steam‑generator water‑level, confirm water supply meets requirement. Power‑on both stenter oven and steam‑boiler unit. Mount fabric specimen onto bidirectional pin‑plate frame, adjust warp‑weft stretching‑tension according to process‑specification. Set target temperature, steam‑mode and holding‑time via main‑control panel. Pre‑heat equipment to reach stable working‑condition.
2. Automatic Sample Feeding Place pin‑plate‑loaded sample onto the inlet station. Activate start‑command; chain‑drive system transports specimen into sealed processing‑chamber automatically. Close the access‑drawer.
3. Steam / Heat‑Setting Processing Equipment executes configured procedure: electric‑heat drying, saturated‑steam ageing or mixed steam‑electric high‑temperature treatment. Circulating‑hot‑air keeps uniform thermal‑moisture environment inside cavity. System counts‑down the pre‑set holding‑duration.
4. Auto‑Discharge & Alarm Notification When timing cycle finishes, the machine automatically pushes the pin‑plate sample‑rack outwards and triggers audible‑alert. Take‑out processed fabric‑specimen.
5. Post‑Test Tidying Run cooling‑fan to lower inner‑chamber temperature for next‑batch‑test. Clean pin‑plate residues and chamber interior. Shut‑down steam‑generator first, then cut‑off main‑power‑supply after equipment fully cools down. Periodically inspect steam‑generator water‑pump, safety‑valve and pipeline connections.
