Here are the key points for cost reduction through bending processing. When manufacturing parts with multiple holes in an angle shape, each hole is drilled individually using a punch or a drill press, which means that the more holes there are, the more processing time is required. Therefore, considering a change to a processing method where holes are drilled in a flat plate before bending is effective for cost reduction. By using a laser processing machine or a turret punch press to drill multiple holes in the flat plate at once, and then performing the bending process, significant reductions in processing time can be achieved. Thus, cost reduction can be achieved through a reduction in man-hours. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce points for cost reduction through bending processing. In the bending processing of sheet metal parts, a bending machine is used, which clamps the sheet between the upper yoke and the lower die. If the groove of the die interferes with taps or holes, it can cause deformation, necessitating corrections in subsequent processes, which leads to increased costs. Therefore, by using a die with a narrow groove, we take measures to prevent interference with taps or holes. This reduces the labor required for corrections after bending processing, allowing for cost reduction. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce points for cost reduction through shape changes in expansion. When joining two parts, there is an increase in welding and finishing processes. Additionally, the occurrence of distortion due to welding heat leads to the need for correction work, which is a problem. Therefore, if there are no design issues such as strength requirements, we can reduce processes by making the parts into a unified structure. This change to bending reduces the welding and finishing processes, resulting in cost savings. Moreover, with the change from welding to bending processing, concerns about the occurrence of welding distortion are naturally alleviated. *For more details, please refer to the PDF materials or feel free to contact us.*

We will introduce points for cost reduction through shape modification during unfolding. There are sheet metal parts that involve welding another flat plate to the side of a bent L-shaped sheet. In this case, the bent area of the L shape bulges, and before welding, it is necessary to grind down the bulged part, which requires additional labor. By cutting the material in advance to create a depression in the bulging area, we can eliminate the bulge after bending. As a result, there is no need for grinding work before welding, allowing for cost reduction through labor savings. *For more details, please refer to the PDF document or feel free to contact us.*

We will introduce points for cost reduction through the expansion shape modification. If the area that becomes the contact surface is angled, it becomes difficult to perform accurate bending without a gauge. If bending is carried out without taking countermeasures, the yield of the product will deteriorate, leading to increased costs. Therefore, we adopt a bending method that includes a leg. This leg is trimmed off after the bending process for finishing. By using this method, accurate positioning for bending becomes possible, improving the yield of the product and achieving cost reduction. *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce points for cost reduction through changes in unfolding shapes. When manufacturing sheet metal parts, it is necessary to attach plates to both sides of the bent sheet material on the top and perform welding operations. By unfolding in this way, the welding work time and the subsequent finishing process labor increase, leading to higher costs. Therefore, by changing the unfolding shape of the sheet metal parts, we can significantly reduce the number of welding points. This results in a reduction in welding time and a decrease in finishing labor, leading to lower processing costs. *For more details, please refer to the PDF materials or feel free to contact us.*

We will introduce points for cost reduction through changes in unfolding shapes. When unfolding sheet metal parts, there is a tendency for the welding bead to become longer, which increases the time required for welding and the labor involved in finishing, leading to higher costs. Therefore, finding ways to shorten the parts that require welding is effective for cost reduction. By changing the unfolding shape and shortening the length of the weld, it becomes possible to reduce the labor for welding and finishing compared to conventional methods, thereby achieving cost reduction. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce points for cost reduction through shape modification during unfolding. In sheet metal assembly processing, dividing and unfolding increases the number of parts, leading to higher costs due to the increased labor required for positioning, welding, and finishing. Additionally, this can cause greater distortion and worsen yield. Therefore, by unfolding into a unified shape that can be handled as much as possible through bending, we can reduce the labor involved in positioning, welding, and finishing. Although the burden of the bending process increases, the reduction in labor for welding and finishing processes is significant, resulting in cost savings. *For more details, please refer to the PDF document or feel free to contact us.*

We would like to introduce points for cost reduction through shape changes in unfolding. Box-shaped sheet metal assembly parts, when divided and unfolded, result in a larger number of components, leading to increased labor for positioning, welding, and finishing, which raises costs. Additionally, this can cause significant distortion, worsening yield. Therefore, by unfolding into a unified shape that can be addressed as much as possible through bending, the scope of welding work can be minimized, reducing labor for distortion correction and finishing tasks. Moreover, the appearance quality is also improved. *If changes to the unfolding are made, confirmation from the designer is necessary. *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce cost reduction points for mechanical assembly. When there are no reference marks for positioning, the installation of parts is done while measuring to ensure that the installation position matches the dimensions on the drawings, which can take a lot of time during assembly work. Therefore, by designing for positioning using dowels, tabs, notches, etc., the positioning of parts during assembly becomes smoother. As a result, the man-hours for assembly work are reduced, leading to cost savings. *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce cost reduction points for machine assembly. Machined parts are often used for mounting bases and spacers. However, as the unit price of parts is high and the number of usage locations increases, the design becomes more costly. Therefore, if there are no issues with dimensions or strength properties, we can reduce costs by using standard square pipes to create bases instead of machined parts, which helps to lower the unit price of the components. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce cost-saving points for machine assembly. When attaching parts to a downward-facing surface, the assembly requires holding the parts upward while tightening with bolts, which takes time for alignment and reduces work efficiency. Therefore, by incorporating hook-shaped notches on the downward-facing surface where the parts are attached, it eliminates the need to hold the parts by hand, thereby improving the work efficiency of the assembly. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce cost reduction points for machine assembly. In labor-saving machines that transport items, mechanisms using slide rails are often employed. When precision is required for the mounting position pitch between two components, it is necessary to perform machining for the fixed positioning of the parts. In this context, one method for positioning between slide rail components is to use dowels. Since it allows for fixed positioning of components equivalent to machining, the labor hours required for machining can be reduced, enabling cost reduction. *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the points of VA/VE in the design of food-saving machinery. Malfunctions of photoelectric sensors can lead to abnormal movements or failures of the machinery. While reflective types are often used due to their simpler equipment configuration, they can be prone to malfunctions caused by factors such as the color of the workpiece or water droplets on its surface. Therefore, it is suggested to consider installation methods that allow for the use of transmissive types. Additionally, using mirror-reflective photoelectric sensors can also be effective. This can help prevent malfunctions of the photoelectric sensors. *For more details, please refer to the PDF materials or feel free to contact us.*

We will introduce the points of VA/VE in the design of labor-saving machinery for the food industry. In the food sector, there are cases where labor-saving machines are made to transfer soft products in bag form. Generally, methods such as suction cups are used to lift these products, but issues such as the bags easily wrinkling or unstable suction can occur. Therefore, a method using a scraper-like tool can also be employed. By pressing down on one end face opposite to where the scraper is inserted, the opposite side that is held down will lift up, making it easier to insert. By adopting this method, the bags are less likely to wrinkle, and the transfer becomes more stable. *For more details, please refer to the PDF materials or feel free to contact us.*

We will introduce the points of VA/VE in the design of food-saving machinery. For units that perform vertical and horizontal movements of machinery, linear bearings are commonly used. The advantage is that they can provide precision in operation, but they require time for positioning during assembly. Therefore, by selecting one side of the shaft with linear bushes, slide rails, or oil-less bushes according to the conditions, and using the other side with resin rollers to serve as guides, cost reduction can be achieved. Additionally, the labor involved in alignment during assembly can also be reduced. *For more details, please refer to the PDF materials or feel free to contact us.

Here are the key points of VA/VE in the design of labor-saving machinery for food processing. In labor-saving machinery for transporting items, conveyors are often used. Typically, straight conveyors and curved conveyors are combined, but it is necessary to connect the straight and curved conveyors. By using a modular belt that can stretch vertically and horizontally on the transport conveyor, it is possible to transport items from straight to curved sections with a single belt. Additionally, since inclines are also possible, by combining straight, curved, and inclined sections, items can be transported from low to high places and from high to low places without the need to transfer between belts. *For more details, please refer to the PDF materials or feel free to contact us.*

We would like to introduce the points of VA (Value Analysis) and VE (Value Engineering) in the design of food processing machinery. The method that has been widely used as a sterilization and cooling device involves placing products in gondolas (such as buckets) connected by chains and transporting them up, down, and sideways while performing sterilization and cooling. However, this method requires complex mechanisms for transferring between devices and takes up a large amount of space overall. By using a spiral conveyor, the mechanism of the device can be simplified. Additionally, it can also achieve space-saving. Furthermore, it can prevent troubles such as the dropping of transported items, making it an effective design method in various aspects. *For more details, please refer to the PDF materials or feel free to contact us.*
