The manufacturing process of our powder feeding machine

For more than 50 years, we have been manufacturing our own powder feeding and dosing machine. Today, we would like to introduce a small part of our process.

We start with the customer’s product design.

An important key point in mechanical design is to first establish clear requirements before design, and then select appropriate materials and manufacturing processes. Designers must consider the balance between product functionality and quality, as well as safety and regulatory compliance. It is also important to consider the manufacturing and maintainability of the product, and to have a flexible system in place to accommodate design changes.


Since screw sizes and shapes vary from customer to customer, it is important to manufacture equipment that can fulfill its role while taking safety into consideration.
We have a variety of machinery and equipment, mainly lathes and milling machines, as well as skilled staff.
Important aspects of machining include maintaining accurate part dimensions and geometry, selecting the proper materials and machining conditions, properly managing cutting tools, ensuring machining accuracy and surface finish, managing safety and the work environment, and implementing an efficient production plan. Proper consideration of these essentials will improve the efficiency and quality of the machining process and ensure product performance.


Welding, in particular, is performed by experienced and skilled craftsmen. In general, the following points are considered when welding powder feeding machine.
1. choice of welding method: Welding arc welding or gas welding is usually used as the welding method for powder feeding machine. Welding arc welding creates an electric arc between the electrode and the work piece. Gas welding, on the other hand, uses combustible gas and oxygen to heat and weld. Which method is used depends on the type of material and welding conditions.
2. choice of welding material: Powder feeding machine handle powdered or granular materials, so the parts to be welded must be made of materials that are resistant to abrasion and corrosion. Typically, materials with high resistance to abrasion and corrosion are selected. For example, wear-resistant stainless steel or hardfacing materials may be used.
3. weld quality control: Due to screw feeders are used to transfer powdered or granular materials, weld quality is critical. Insufficient strength and durability of the welds can interfere with material transfer. Therefore, it is important to properly quality control the entire welding process.


Machine assembly is the process of properly combining designed parts to complete a functioning product. The assembly process involves the following important aspects
1. checking design drawings: Before starting assembly work, thoroughly check the design drawings and assembly instructions to understand the order of assembly and the positioning of parts.
Inspect and prepare parts: Inspect parts and components to be assembled to ensure that they are free of defects or defects. Clean parts as required and prepare necessary tools and lubricants.
3. follow assembly procedures accurately: Assemble parts correctly according to assembly instructions. Proper sequence and application of appropriate torque and tightening force will ensure that parts are properly joined together.
4. testing and adjustment: After assembly is complete, the product is tested for operation and adjustment. If necessary, adjustments are made to ensure that functions and performance meet requirements.
5. quality control and inspection: Quality control and inspection are performed on the assembled products. Check the accuracy of parts and quality of assembly, and make corrections and re-inspections as necessary.
6. documentation and records: Document and maintain information and records related to assembly operations. Documentation such as product assembly procedures, test results, and quality inspection reports are useful for future reference and quality control.

Adherence to these essentials will ensure efficient machine assembly operations and product quality and reliability.

We do all of the above work in-house, without outsourcing. This allows us to respond quickly and flexibly, which is one of our strengths. We strongly hope to continue to deliver our equipment to customers not only in Japan but around the world.
