ZESTIA List of Products and Services

We would like to introduce a case study on the design and manufacturing of the "Food Packaging Machine (Interior)" developed by Achi Seiki Co., Ltd. This product is a packaging machine designed for packing food (powder) using non-woven fabric. When we were initially commissioned to create this packaging machine, there was, of course, a request for cost reduction. However, since our company conducts machining in-house using machining centers and lathes, we proposed changes to the component shapes that would reduce assembly labor, thereby achieving overall cost benefits. [Case Study: Challenges] - Cost reduction - Weight reduction - Improved accuracy *For more details, please refer to the related links or PDF materials, or feel free to contact us.

We would like to introduce a case study on the design and manufacturing of the "Food Packaging Machine (Interior)" developed by Achi Seiki Co., Ltd. This product is a packaging machine designed to package food (powder) using non-woven fabric. Upon receiving a request from a customer, we handle everything from parts processing to assembly, electrical work, adjustments, and program installation before shipping. The machine was designed with the goal of reducing costs while improving performance compared to conventional machines. We proposed detailed processing and assembly solutions from the design stage, creating a device that excels in cost performance as per the customer's objectives. [Case Study] ■ Customer's Intentions - The customer wanted to develop and sell an integrated machine using equipment from another manufacturer. - They also wanted to reduce the weight of the machine. ■ Result: High-performance components were created without compromising functionality. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

• Binding/Packing Machine

We would like to introduce a case study on the design and manufacturing of the "Food Packaging Machine (Outer Packaging)" developed by Achi Seiki Co., Ltd. This product is a packaging machine designed for individual packaging of food products. Upon receiving a request from our customer, we handle everything from part processing to assembly, electrical work, adjustments, and program installation before shipping. There were similar post-welding processes that required different jigs, and there were challenges related to weight reduction and precision improvement. Therefore, we collaborated with the customer's development team to select and design materials and shapes, standardizing certain aspects such as shape and welding methods. This allowed for processing with the same jig, resulting in cost reductions for the customer's machinery (reducing the number of jigs from 4 to 1). 【Case Study】 ■Challenges - Similar post-welding processes required different jigs. - Weight reduction. - Precision improvement. ■Results - Enabled processing with the same jig, leading to cost reductions for the customer's machinery. *For more details, please refer to the related links or PDF materials, or feel free to contact us.

• Binding/Packing Machine

We would like to introduce a case study on the design and manufacturing of the "Food Packaging Machine (Interior)" developed by Achi Seiki Co., Ltd. This product is a packaging machine designed for the individual packaging of food products. Upon receiving a request from a customer, we handle everything from part processing to assembly, electrical work, adjustments, and program installation before shipping. When processing and assembling, it was crucial for each unit to align properly; however, the reference points were ambiguous, making assembly and maintenance difficult for operators who were not well-versed in the equipment. To address this, we added reference knock pins to each unit and established an assembly sequence, which allowed us to reduce assembly man-hours and improve reproducibility during maintenance. [Case Study] ■ Challenge: Assembly and maintenance were difficult for operators who were not familiar with the equipment. ■ Results: - Reduced assembly man-hours - Improved reproducibility during maintenance *For more details, please refer to the related links or PDF materials, or feel free to contact us.

• Binding/Packing Machine

We would like to introduce a case study on the design and manufacturing of the "Labeling Device" developed by Achi Seiki Co., Ltd. This product is a sub-assembly used in the labeling line for bottles and jars. We manufacture and assemble multiple units used for movements in the front-back, left-right, and up-down directions. Initially, we were creating it by adding processing to the supplied aluminum castings, but we found that it was not sufficiently fulfilling the necessary functions for the mechanism. After providing technical proposals, we conducted a prototype using "machined aluminum" and received customer approval for design changes. By switching to machined aluminum, stable processing became possible. [Case Study: Manufacturing Results] - Surface treatment changed from painting to hard anodizing - Reduced the labor involved in masking for tolerance holes, which increased overall strength - Stable processing became possible by switching to machined aluminum *For more details, please refer to the related links or PDF materials, or feel free to contact us.

At Achi Seiki, we continuously conduct surveys on the usage and content of substances regulated by the RoHS Directive for materials and supplies procured during the manufacturing of our products. In implementation, we operate a "RoHS Directive Compliance Management System." Based on regulatory requirements and customer demands, we are working on considering alternatives in cases where regulated substances are present and on eliminating those substances. We can also provide certificates of non-use of substances, ingredient lists, and environmental documentation. Please feel free to contact us for any requests or inquiries regarding the RoHS Directive. 【Features】 ■ Operation of the "RoHS Directive Compliance Management System" ■ Continuation of the system for RoHS2 compliance activities and implementation ■ Provision of certificates of non-use of substances, ingredient lists, and environmental documentation is also possible *For more details, please refer to the external link or feel free to contact us.

• Contract Inspection

At Achi Seiki, we manufacture for the food industry, medical device industry, image inspection machine industry, bearing production machinery (related to grinding), and OEM manufacturing of machinery. We perform assembly adjustments and electrical work with expertise in each industry. About 70% of the machines we assemble are exported overseas, and we can manage mill sheets and produce according to CE standards without any issues. Since we also handle design and machining in-house, we can provide comprehensive proposals and manufacturing. 【Features】 ■ We can manage mill sheets and produce according to CE standards without any issues. ■ We adjust the machinery so that it can be used immediately upon delivery or delivered (OEM). ■ We design machinery tailored to customer specifications. ■ We can provide comprehensive proposals and manufacturing. *For more details, please refer to the external link or feel free to contact us.
