Food Processing – Improving Hygiene & Assembly Efficiency for a German Bakery Equipment Manufacturer

Client Background

A medium-sized German manufacturer of commercial bakery production lines faced frequent loosening and corrosion issues on standard nuts used in their dough mixing and conveying equipment. The existing fasteners required replacement every 4–6 months due to high humidity, frequent washdowns with acidic cleaning agents, and constant vibration.

Challenge

The client needed non-standard fasteners that could withstand high humidity, mild acids, and constant vibration. Standard DIN nuts failed in less than half a year. They also required a customized shape for a space‑constrained tightening tool path.

Our Solution as Jiangsu Bafang Metal Manufacturing Co., Ltd.

Material & Grade: Supplied 316 stainless steel nuts (higher corrosion resistance than 304) in custom non-standard dome‑top shape, eliminating debris accumulation and making cleaning easier.

Precision Manufacturing: Manufactured as OEM components directly from their 3D drawing. Achieved dimensional tolerance within ±0.02mm, ensuring a perfect fit on the existing bolt series.

Quality Assurance: All nuts were 100% fully inspected and supplied with CE certification and ISO9001:2015 documentation. The RoHS compliant surface treatment met EU food contact standards.

Prototyping & Lead Time: Produced a 7‑day prototype for real‑machine testing. After approval, full batch delivery was completed in 15 days.

Result

Nut service life extended from 6 months to over 24 months.

Reduced unplanned downtime by 70%.

The German customer placed three repeat orders and now sources 80% of their non-standard fastener requirements from Jiangsu Bafang.
