The following is a case study of a customer application of screws from Hanshin Neji (Thailand) Co.,Ltd. , a fasteners trading company that supplying the screws to Thai Forging Engineering Co., Ltd. (hereinafter referred to as TFE), which is engaged in the hot forging of mechanical parts.
Thai Forging Engineering Co., Ltd. (TFE), founded in 1991, is a renowned manufacturer of mechanical parts offering forging services to industries such as agriculture, automotive, and construction. Beyond serving the domestic market in Thailand, TFE also extends its supply chain to international markets, including the Philippines, Indonesia, and various European nations.

TFE has achieved ISO 9001:2015 and IATF 16949:2016 certifications, affirming its status as a top-tier manufacturer of quality parts. The Quality Control (QC) department, play a crucial role in every stage of production from material inspection, machined parts and molds used in manufacturing process, and conducting final inspection of finished products inspection to ensure that only parts meeting the highest quality standards are delivered to customers.
Along with traceability system in every process, when problem or irregular event occurred, they can immediately investigate and take action at the source of the problem.
TFE has taken a significant step to address the rising demand for electric vehicle (EV) components. By installing new machines and setting up operations in aluminum hot forging, TFE is well-positioned to serve the expanding EV market.
In the hot forging process, it is essential to securely tighten the clamps on the mold and machine due to the immense force will be applied during operation. The fastening screws used must be high tensile strength type, conforming to the standard, to guarantee a stable and efficient forging process.
Before the introduction of Hanshin Neji’s fasteners, TFE was encountered several fasteners issues such as loosing and breaking screw during machine operation. Leading to a reduction in product quality and an increase in maintenance time due to the instability of the fasteners.
“After integrated quality screws to our specifications, we’ve observed a significant increase in the product lifespan, now lasting up to six months. As our required fasteners are unique sizes, we reply on importing service from Japan. Despite this, Hanshin Neji consistently meets expectations with prompt responses and the ability to accommodate our urgent requirements.”
(Mr. Bunchai, Director of TFE)
The challenges faced by TFE originated from the substandard quality of screws utilized. Applying screws that failed to meet quality benchmarks resulted in damages such as thread breakage, which lead to issues including a reduced lifespan for screws and stop in the production line as well as the need of machinery repairs. After Hanshin Neji’s screws application, these quality-related issues were resolved, and screws lifespan increased up to three times. Moreover, TFE has achieved a reduction in work hours and labor expenses, as well as capability to forecast a comprehensive maintenance schedule.”
"We have been using screws from Hanshin Neji for five years and we are very satisfied with their high-quality products with reasonable prices. We have never had any problems of their product application” (Mr. Bunchai, Director of TFE)
Additionally, providing high-quality screws with expedited delivery time along with technical consultant services, create one of Hanshin Neji core competencies. Fasteners are such small components, but they play significant roles that directly impact to product quality and production efficiency. Hanshin Neji is committed to ongoing resolution of fasteners-related issues in Thailand.
