Company profile
AISHENGKE (JIANGSU) CHEMICAL TECHNOLOGY CO., LTD., also identified as ASK, is based in Changzhou and specializes in high-purity semiconductor materials, CVD and ALD precursor containers, and related supporting services. The company describes a professional R&D team and an industry patent portfolio, follows EP-level clean standards, and provides products and customized solutions to semiconductor customers globally. Its stated operating priorities are technological innovation, stable quality, long-term cooperation, and joint progress with customers in the semiconductor industry.
Exhibits
ASK's MO, CVD, and ALD precursor storage and delivery system is designed for liquid, gas, and solid precursors used in Atomic Layer Deposition and Chemical Vapor Deposition processes and is intended to provide stable mass flux for a wide variety of current and future process materials. Its product categories include CVD and ALD delivery systems and pressure vessels, covering the precursor-container and delivery requirements referenced in its semiconductor-material business. The molecular-distillation portfolio includes laboratory short-path distillation equipment, molecular-distillation systems, application-oriented molecular-distillation units, glass and stainless-steel fractional-distillation units, and rotary evaporators. Its wiped-film and thin-film evaporation range includes laboratory, pilot-scale, and continuous-production equipment, while the reactor range includes small laboratory reactors, pilot glass-reactor systems, lifting glass reactors, lifting stainless-steel reactors, and continuous pilot-scale reactors. ASK also lists vacuum pumps, heating systems, cooling systems, and combined refrigeration-heating systems as optional supporting equipment, together with user-manual, distributor, sales, and customized services. Molecular distillation, also described as molecular still, short-path still, or short-path evaporation, is intended for difficult thermal separations involving heat-sensitive materials. In the described process, feed enters a vertical heated cylindrical chamber at a fixed rate and is actively wiped into a turbulent thin film under high vacuum so that more volatile components evaporate efficiently. The short-path design uses vacuum-lowered temperatures and residence times measured in seconds, and collects two cooled product streams, distillate and residue, to minimize degradation while preserving product quality, yield, and value. ASK offers a borosilicate-glass molecular short-path distillation system described with high evaporation efficiency, suitability for varied material types, and capacity from 1 to 500 L/h. The company also lists laboratory-scale, pilot-scale, and industrial-scale short-path distillation units so the separation approach can be applied across development, scale-up, and continuous-production requirements. For continuous industrialization, ASK combines a wiped-film evaporation system with a short-path distillation system and can add filtration modules, rectification modules, and other modules according to customer process requirements. The thin-film evaporator can be used before molecular distillation for pretreatment tasks such as degassing, solvent removal, and removal of small molecules, reducing risks of splashing, flash evaporation, degradation, or separation failure when material first enters the evaporation chamber. The combined thin-film evaporation and short-path design is described as improving the production efficiency of short-path distillation by preparing the feed before the final molecular-separation stage. For pilot or industrial short-path evaporation, ASK lists systems built around raw-material tanks, short-path stills, cold traps, valves and pipe fittings, inlet and outlet pumps, two-stage vacuum systems, and control systems. The main equipment in that stainless-steel pilot or industrial configuration is specified as 316L stainless steel. ASK separately identifies Wiped Film Molecular Distillation Equipment within its molecular-distillation product range, placing wiped-film operation alongside other short-path system configurations. A stainless-steel vacuum wiped-film molecular-distillation system is listed for pilot and industrial service, with the described pilot or industrial plant using 316L stainless steel for its main equipment. The product family is also presented as Laboratory & Pilot Test & Continuous Short Path Distillation Unit/System, explicitly spanning laboratory trials, pilot testing, and continuous-operation configurations. Within fractional distillation, ASK lists both glass and stainless-steel fractional-distillation units and also lists rotary evaporators as a separate process-equipment category. Together, the portfolio links high-purity semiconductor materials and precursor containment with CVD and ALD delivery, laboratory and production distillation, thin-film evaporation, fractional distillation, reactor systems, vacuum and thermal-control accessories, and customer-specific system configuration.
