Complete Production

  Stairs Industrial Co. Ltd. has significantly amped-up its gears to enhance and monitor the quality of its pumps. Initially, product assembly was to commissioned sub-contractors, resulting to quality control dominantly resting in the hands of suppliers.

  However, it became apparent that to safeguard the product's compliance to standardized quality specifications, all component parts it was created with, must first and foremost adhere to the same.

  With that being the motivation, Stairs gradually brought home as much production processes as possible. Now, approximately 95% of all parts used in the production of pumps are manufactured in-house, enabling the company to implement design changes quickly and execute quality conformance more strictly.

  Stairs has invested heavily in machineries to facilitate this evolution, which resulted to complete control of nearly all production stages there is including mold design, production, stamping, welding, cutting, grinding, polishing, injection molding, assembly, testing, and packing. The company can now confidently guarantee the high quality of its product armory.

Quality Certification

  Stairs Industrial Co. Ltd. has seriously invested in state-of-the-art test equipment, sourced from both domestic and international suppliers, to ensure that all components and finished products are compliant with stringent specifications. Our production operators are fully equipped with the necessary gauges, tooling, and standard operating instructions to guarantee the top-notch quality of their workmanship.

  To further reinforce our commitment to quality and reliability, we have purposely established a formal Quality Assurance program under the conscientious supervision of our Quality Control Department, which has enabled us to meet the requirements of ISO 9001 QMS principles.

  We also have a streamlined training and retraining program for all production staff to ensure they remain up-to-date with the latest techniques and methodologies. All of these efforts are geared towards maintaining and sustaining our foremost mission that Stairs Industrial Co. Ltd. ceaselessly provides top-grade pumps and exceptional sales and after-sales services to our valued partners.

PRODUCTION PROCESS
COMPLETE

STAIRS's own foundry

  We have our own foundry for investment casting where we produce cast stainless steel parts for our pumps. The investment casting process provides incredible design flexibility, numerous material options and superior quality. Best of all, investment casting is typically more cost effective than traditional casting methods.

  The precision casting process is controlled and monitored by a computerized quality control system.
Composite testing is done with a sophisticated spectrometer. Manual checks are conducted continually to further ensure quality.

Highest quality of stainless steel

  The use of stainless steel plays a vital role in our production process. The stainless steel arrives in large rolls of sheet at our factory, is processed into parts and finally leaves our factory as high grade pumps. The quality of the stainless steel is critical in making the pumps highly reliable and durable. The quality of the steel is especially crucial in potable water and process water applications.

  Taiwan is well known for its high quality of stainless steel. In our production process we use two different types of stainless steel: stainless steel AISI 304 and AISI 316. The second type is more corrosion resistant than the first and is therefore used for aggressive liquids and process water.

Molds

  We use more than one thousand molds to produce parts for our pumps. The quality of the stamping molds is important in controlling the precision of the stampings and thus quality and consistency of the parts. CAD and CAM systems are used in controlling the design and manufacturing process that assures dimensional and component integrity.

Welding Technology

  Our skilled stainless steel welding technicians realize that every step in the process of stainless steel welding is important and contributes to the overall quality of the pumps.
Our trained welders know and appreciate the difficulty and complexity of stainless steel welding, allowing them to consistently achieve levels of quality that are hard to come by. Though stainless steel is a popular welding material, due to high thermal expansion, it is prone to warping and distortions during the welding process. Our welders pay close attention to the metal's microstructure in order to prevent cracking and deformation, and due to this careful attention to detail, are able to achieve the high quality for which Stairs pumps are known.
More
  To complement our highly skilled welding technicians, our welding department contains some of today's most advanced welding equipment and instruments, giving our welders the tools and technology to help them consistently complete demanding welding projects.
  We use the following welding methods to produce the highest quality of pump components.

Machining

  Pump parts require strict tolerances for quality. In 2000, STAIRS made a conscious decision to move into manufacturing more of its own parts. This has resulted in a heavy investment program equipping the company with a range of CNC milling and turning machines. These machines complement and enhance the existing manual machines that equipped our machining department.

  Our machine shop has full fledged inspection facilities including digital height gages, surface table and other inspection measuring & testing equipment.

  In-house, as well as outside training programs for our technicians assure knowledgeable and highly qualified staff to complement our modern production equipment.

Assembly

  We have two assembly factories for industrial pumps and borehole submersible pumps. The complete assembly lines are designed for efficient assembly, calibration and testing. After a final inspection, pumps are then packed and prepared for shipment.

  These streamlined production lines have allowed us to achieve cost savings by reducing manpower requirements, cycle times, reject rates and increasing overall efficiencies, while at the same time increasing production capacity and maintaining our high quality standards.
