Quality standards for the products we handle
At Daio Seisakusho, customers handle the products they handle.“I can understand it sensuously”Quality classes are assigned and classified.
- There are five levels of appearance quality from S to D.
- The performance (function) of parts is expressed in three stages from 1 to 3, and is displayed in combination with the above appearance quality (five stages).
- Good product requirements for miscellaneous goods are represented by the applicable items from a to h, and are displayed in combination with the above appearance quality (five levels).
About appearance quality
| Classes | impression | Scratches/dirts/unevenness/roughness/burrs | Target of use |
|---|---|---|---|
S |
Beautiful finish | Difficult to see * 1 * 2 | ・Branded goods, luxury accessories, etc. |
A |
Almost clean finish | If you look closely, there are slight scratches and color unevenness, but it is always inconspicuous * 1 * 2 |
・Accessory miscellaneous goods ・Relatively expensive souvenirs and gifts |
B |
Appearance quality with no problems in use | There are small scratches, burrs, and slight uneven finish.There is some roughness in the smoothness of the surface. | ・Reasonable accessories ・Small items such as bag metal fittings that occupy a small area of the product .Used in less noticeable parts |
C |
The quality is somewhat unsatisfactory | There are scratches and uneven finish that can be seen at a glance. There is roughness in the smoothness of the surface. Bali doesn't hurt as it gets caught in the finger pad. |
・Inexpensive novelty ・Distribution ・Use in inconspicuous parts |
D |
There is no dignity and outside appearance * Products specializing only in functions and prices |
The appearance is notable for roughness, but there is no adverse effect on function or performance. There is no danger Bali. Handles defective products such as chips, rust, mold, and painful burrs. | ・Parts and tools ·the expendables |
(* 1) This is a name-entry / decorative product, and the appearance grade of the area that is supposed to be blindfolded by post-processing (such as attaching a decorative sticker) is class B.
(* 2) The appearance grade of the movable structure that is normally closed and becomes a blind spot, and the surface that is closed and becomes a blind spot when combined with other articles is Class B.
Performance of parts (excluding electrical products and daily miscellaneous goods)
| Classes | Image of usability | Opening/Closing/Detaching/Expansion/contraction/Elasticity/Springiness | Target of use |
|---|---|---|---|
1 |
Smooth Always comfortable to use. |
Opening and closing and putting on and taking off are not too tight or too loose. There is a proper feeling of operation (click feeling, etc.) |
.Variants that frequently operate moving parts (such as wallet opening and closing fittings) .Used by the elderly and small children on a daily basis ・Relatively high-quality sundries |
2 |
Average smooth Allowable range of slight discomfort (listed on the right) |
It can be opened and closed and put on and taken off almost smoothly, but it may be a little hard or loose.It has a spring-loaded opening and closing structure, and although it may get caught when opening and closing, it automatically returns to the origin. | -Items that are used on a daily basis but do not operate frequently (such as metal fittings for belts on bags and photo frames) ・Relatively reasonable sundries |
3 |
Somewhat coarse | It may get caught when opening/closing or attaching/detaching, but it fulfills its original purpose. The spring sometimes does not work well, but it will return to the home position with a little manual support. |
・ Movable parts that are used infrequently (containers for lost cards, etc.) ・It is OK if it finally fulfills its purpose |
Goods requirements for miscellaneous goods
| categories | Product requirements | Defective product | Our target products |
|---|---|---|---|
a All Items Common items |
1) Based on the specified specifications (dimensions / materials / colors / strength / operability / functions, etc.) 2) To play the original role of the product 3) Designed with safety in mind or caution signs 4) Compliance with the laws and regulations to which the product belongs 【Tolerance】 ・ Errors between production lots of paint and dyeing colors ・ Individual differences of hand-painted products, errors between lots [Others] ・ Implementation of measures against the assumed defect rate (preliminary disclosure of defect rate, attachment of spare parts, etc.) * Complaints about products that are one month old after delivery are out of the scope of free support within the range of quality and specifications confirmed in advance with materials and samples. (In the case of a customer's custom-made product, it is out of the scope of free support regardless of the elapsed period after delivery) |
1) There is a clear difference between the specified specifications and the actual product. 2) Does not fulfill the original role of the product and does not meet common sense expectations 3) Products with clear individual differences compared to others 4) The user cannot supplement within the range of common sense (Example of complement: cutting of protruding thread, retightening of loose screws, etc.) 5) Deformation, discoloration, rust, mold, etc. of unused products under general storage conditions are observed (excluding deterioration due to characteristics notified in advance). 6) Products that have not been found to have common sense safety within the range of normal storage and use even within the specifications. [Others] ・ Unexpected abnormal noise, odor, vibration, heat generation, etc. that are not related to the original characteristics ・ Some products are not covered by the warranty for stains and deformation of the package (we will check in advance). |
Common to all products |
b Container / case |
・ Can be opened and closed with moderate force -Has strength suitable for normal use ・ Sanitation suitable for the specified use |
・ Opening and closing operability is not suitable for the user group and applications (too tight / too loose, etc.) ・ There are looseness and gaps that may cause the contents to leak. ・ Sanitation is not suitable for the application |

h Electric appliances |
-Products that come with batteries must have a battery capacity that can be tested for operation at the time of delivery. ・ Functions can be used with common sense operations ・ Stable output can be obtained ・ Usability such as operating noise and vibration can be used within the range of common sense. [Points to keep in mind for each product type] 1) Luminous product ・ It can output the amount of light suitable for normal use. 2) Audio equipment -Can output volume and tone suitable for normal use 3) Movable equipment (fans, etc.) ・ It is possible to output the operation and power suitable for the purpose of use. ・ Implementation of contact measures (safety measures) for moving parts ・ Operating noise and vibration are within the range suitable for the purpose of use. 4) Display ・ Has visibility suitable for the purpose of use 5) Charger ・ Compliance with applicable standards |
・ Rust and liquid leakage from batteries and terminals -The capacity of the attached power supply at the time of opening is so low that the operation test cannot be performed. ・ Even though they are used under the same conditions, their performance is clearly inferior to others. ・ Output is unstable ・ Abnormal noise, odor, vibration, and extreme heat generation during operation |
