1. Raw materials
a. Content and thickness of copper in copper material?
A: The copper content of different labels is different from that of copper. Currently, copper commonly used in the button industry is H62 copper (60.5-63.5), H65 copper (63.5-68.0), H68 copper (67.0-70.0), and the thickness of copper tape. According to product requirements, the thickness of the company's current copper strip is between 0.16mm-0.80mm.
b. Composition of alloy raw materials?
A: At present, the company uses 3C# zinc alloy, its main components are zinc and aluminum, followed by magnesium, copper, iron, lead, cadmium, tin.
c. Can the above materials pass the needle detector or needle detector?
Answer: The above raw materials can pass the needle detector. The number of machine grades depends on the label of the product's material, the number of products passed, the method of placing the product when it passes, and the type of the needle detector.
d. Is there a test report?
A: The supplier can provide the quality assurance certificate or laboratory report of the raw materials, so you can check the relevant chemical composition and test item values.
2. Plating color
a. Is there a reference color card for plating?
A: At present, the domestic electroplating factory only has "Lu's International Standard Plating Color Card."
b. Can plating color achieve environmental protection tests?
A: The product plating color can meet the requirements of environmental testing.
c. Will the plating color fade?
A: Over time, electroplating products will be affected by the weather, environment and operating conditions, and there will be a difference in color contrast when they are electroplated. All electroplating products do not include “washing water.†If guests have special requirements for the button surface coating, Before the order is submitted, it can be considered as a "powerhouse" and "protection
Acid force frame" protection and so on.
d. Can the plating color be plated with the color of the foot plate?
A: At present, domestic electroplating factories are all manual operations. The master controls the electroplating additives and plating time. It is not like the foreign computer controls the entire electroplating process. Therefore, it cannot guarantee the electroplating with the electroplating of the full-color plates, and even the same batch of different cylinders will have color differences. Only the similarity between swatches and swatches can be guaranteed to be between 80% and 90%. When the swatches are different from the substrate of the products to be swatches, the comparable degree will decrease.
3. The strength of the product
a. The strength value of the product varies according to the structure of the product and the test methods are different: the points of pressure, tension, sustainability, and destructive power.
b. The pressure and tension values ​​in the above strength values ​​will be different when the plating color of the product is different. The sustainability force and the destructive force will be different depending on the thickness of the materials used. The specific strength values ​​can refer to the relevant standards of the company.
4. Why are some of the three urgencies under the escalator tight?
Answer: a. The company's products all have their standard dimensions, as long as the difference in force values ​​is not too large within the tolerance range.
b. The pulling force and pressure value of the squeezing button will be different due to the difference in plating color. For example, the lightest color is the dark color, and the black color and the dull color are relatively tight. You can use the product to solve the problem of water-skidding (wax water). Secondly, it is related to the thickness of the cloth when the product is nailed, and whether the product after the nailing is deformed (such as the elastic size becomes larger after the fight).
c. If the customer has special requirements on the strength value, the product size can be improved if necessary.
5. Can the product be environmentally friendly?
A: The product can be environmentally friendly, but the customer needs to put it forward before the order is placed. The company will control it from the raw materials and production process to ensure it.
6. Why is the English letter burst after the nail is put on the corn product?
Answer: a. It is related to the thickness of the product materials, the depth of the English mold engraving, and the post-processing of the mold (slip angle).
b. It is related to whether the moulding is matched with the shape of the corns and whether the height of moulding adjustment is correct.
7. Alloy cap nail stick drill products will be dropped after drilling, broken drill?
Answer: a. Relevant to the product structure, in principle, the alloy cap nail product should be moulded instead of sticky diamond, especially when the diameter of the drill exceeds 40%.
b. It is related to the toughness of the glue used for viscose drilling, and a small part is related to the material and design of molding materials.
8. Spray paint surface and foreign particles in the paint?
Answer: a. Fuel injection products collide with each other due to friction, and in particular the flute mouthpiece hangs the top coat. Therefore, in principle, the injection product is packaged into a plastic bag after copying paper packaging.
b. Particulate foreign matter on the surface of the fuel injection product is caused by the paint slag or the original debris on the surface of the product being covered by the paint.
