Huong Sen Textile Fiber Company improves the overall equipment performance

Huong Sen Comfor Textile Co., Ltd. was built from July 2018 and put into operation in 2019. This is a spinning factory with advanced and modern technology with imported machinery and equipment. European products from famous brands: Rieter, Electrojet, Savio, Luwa, etc. The factory’s capacity is 6,000 tons / year, serving the domestic market and exporting abroad.

With the desire to master machinery and equipment, right after stabilizing production operations, the factory participated in the Overall Productivity Maintenance (TPM) program supported by the Ministry of Industry and Trade from May 2020 and achieved received many remarkable results.

OEE overall equipment performance index is established and monitored at the bottleneck of the chain and continuously analyzed for opportunities for improvement. After 6 months of implementation, OEE increased from 84.44% (June 2020) to 89.66% (October 2020). To achieve this result, the staff of the plant’s maintenance and operation departments have been continuously learning, standardizing operations and internal training to ensure that equipment is operating stably and increasing reliability when operating.

Equipment maintenance chain schedule is elaborated by the technical team together with consultants to elaborate on the items of the machine together with operating instructions, maintenance standards and standardization of tools and tools needed. From there, a maintenance plan is developed and estimates how much time is needed before performing the maintenance from the weekly through to the annual maintenance schedule. This plan is informed in advance to the production department so that all parties can actively work to reduce unnecessary waiting time. From the equipment maintenance plan built and effectively applied at the sub-machine stage, the host factory actively replicates and builds detailed plans for the remaining machines. The result when the equipment is 100% compliant with the maintenance schedule is that the unplanned downtime has been reduced from 10,270 minutes (June 2020) to 5,495 minutes (October 2020).

Along with the maintenance team, the technology worker group in charge of equipment operation is also actively involved in taking care of basic equipment, recording and handling abnormalities early at the equipment. The number of anomalies detected and processed at the client domain from June 2020 to November 2020 is 350 anomalies. This data is statistically and analyzed, showing frequent recurring problems such as gas puck errors and gas line breaks. With frequent fault locations, maintenance staff participate in handling, drawing lessons learned and internal training so that when operating, they can quickly judge the cause and reduce the time to fix it.

With the efforts of the maintenance and operation departments of the equipment, the efficiency loss at the client has been reduced from 9.34% (June 2020) to 5.45% (October 2020). The results achieved have supported the goal of improving OEE and completing the assigned tasks when implementing the TPM program at the factory.
