[Case Study] Prevention of Foreign Matter Contamination in Food Manufacturing Lines and Reduction of Inspection Work

[Case Study] Prevention of Foreign Matter Contamination in Food Manufacturing Lines and Reduction of Inspection Work

A case where Nord-Lock washers were proposed to prevent the loosening and falling out of screws.

Here is a case where we proposed the "Nord-Lock Washer" to a food processing manufacturer. In the final stage of packing the manufactured liquid, screws used in the equipment line fell off and were shipped without anyone noticing, resulting in contamination of the product. After our proposal, there have been no signs of screw detachment, and the emergency measure of inspection work has been eliminated, leading to a reduction in the burden on the workers. [Overview of the Issue] ■ Screws used in the equipment line fell off and were shipped while contaminating the product without anyone noticing. ■ The issue was discovered by chance during an inspection at a retail store, leading to a halt in production and a recall of all products. ■ Since then, all areas with potential for detachment have been addressed with emergency measures. ■ The inspection work before starting operations has become an excessive burden, so we want to implement a fundamental solution. *For more details, please refer to the related links or feel free to contact us.

Warning of bolt loosening with color! Axial force management "DTI System"

Warning of bolt loosening with color! Axial force management "DTI System"

Visual axis force management! Completion with pinpoint work only at the fastening points indicated in red for looseness occurrence!

The "DTI system" is a torque management system that embeds a mechanism within the bolt to detect slight elongation caused by axial force, displaying the degree of elongation (i.e., axial force) through a color change from red to black. Insufficient axial force due to improper tightening during bolt fastening operations increases the risk of breakage and other issues. By using this system, it is possible to confirm that the planned initial axial force has been achieved at all fastening points. Since the appropriate axial force varies depending on the application, it will be determined in consultation and produced to order based on the intended use. 【Features】 ■ Improves the safety of bolt fastening assemblies by accurately grasping axial force (i.e., tightening force) ■ Constant display of axial force allows for early problem detection and trouble avoidance ■ Enhances equipment operational efficiency through pinpoint maintenance *For more details, please download the PDF or feel free to contact us.

[Case Study] Cost Reduction through Changes in Manufacturing Method of Mass-Produced Screws

[Case Study] Cost Reduction through Changes in Manufacturing Method of Mass-Produced Screws

A case where the manufacturing method was changed from cutting processing to forging processing, resulting in a 70% cost reduction in the customer's purchase unit price.

We would like to introduce a case where we proposed "reducing the manufacturing process and increasing production lots" to an industrial machinery manufacturer. The customer was purchasing low-head type special-shaped hexagon socket bolts M2 from an e-commerce site, but they had a request to reduce costs due to the high unit price and increasing usage. We proposed a change in the manufacturing method, which was adopted without any issues and met or exceeded the performance of the conventional products, resulting in significant cost reduction. [Case Overview] ■ Issues - Costs had become too high - The shape was not particularly difficult to manufacture, despite being outside JIS standards ■ Requirements for Solving the Issues - Reduction of costly machining processes - Establishing production lots that ensure stable lead times *For more details, please refer to the related links or feel free to contact us.

[Case Study] Coating the Head of a Left-Hand Thread Hex Socket Bolt

[Case Study] Coating the Head of a Left-Hand Thread Hex Socket Bolt

Production completed in time for the desired delivery date! A case of proposing alternatives for discontinued products from the manufacturer.

We would like to introduce a case where we proposed an alternative for hexagon socket bolts with left-hand threads that have disappeared from the market due to the manufacturer's discontinuation to a textile machinery manufacturer. The M3×7 hexagon socket bolt (left-hand thread) used in textile machinery was discontinued, and without finding an alternative product, the production line would come to a halt, affecting sales. We proposed custom machining of the left-hand thread hexagon socket bolts and painting of the heads, allowing for the selection of right-hand and left-hand threads without changing the screw size, and we were able to deliver the product by the desired deadline. [Overview of the Issue] - The M3×7 hexagon socket bolt (left-hand thread) was used in textile machinery, but production by the manufacturer has ended and it has been discontinued. - If no alternative product is found, the production line will stop, impacting sales. *For more details, please refer to the related links or feel free to contact us.

[Case Study] Investigation and Measures for the Cause of Loosening

[Case Study] Investigation and Measures for the Cause of Loosening

A case study proposing investigation and measures for the loosening of embedded bolts used to secure tire wheels.

We would like to introduce a case where we proposed the identification of the cause of loosening and permanent countermeasures through hypothesis establishment and dimensional inspection using an image measurement device for an industrial vehicle manufacturer. There was an issue where the embedded bolts used to secure the forklift tire wheels would fall off after delivery to the customer. We shared knowledge regarding the embedded bolts and conducted dimensional measurements of the threaded parts using the image measurement device. We proposed clearly stating tolerances on the drawings to ensure accurate communication of information among design, quality control, procurement, and suppliers. [Overview of the Issue] ■ The embedded bolts used to secure the forklift tire wheels fall off after delivery to the customer. ■ If they fall off during operation, it could lead to a serious accident, so it must be resolved urgently. *For more details, please refer to the related links or feel free to contact us.

[Technical Column] Do you know the difference between implant bolts and double-ended bolts?

[Technical Column] Do you know the difference between implant bolts and double-ended bolts?

Actually different! I summarized the specific differences between "insert bolts" and "double-threaded bolts."

Both the implant bolts and double-ended bolts have no heads and are products with threads cut on both ends, and they are sometimes thought to be the same product, but in fact, they are different. Recently, I received a consultation stating, "There was a loosening in the double-ended bolt that is securing the machine." It seems that the person was not aware that the effective diameter of the threaded part on the implant side of the implant bolt is slightly thicker, which was the cause of the loosening. If such issues are discovered after mass production, it can lead to serious problems. To prevent this, let's recognize the differences between "implant bolts" and "double-ended bolts." *For more details on the column, you can view it through the related links.
