In addition to data control during mould manufacturing and injection moulding, perfect products should be injected. More relevant experience is needed in the design and manufacture of dustbin mould. According to the characteristics, sizes and shapes of different materials, the pre-design evaluation and analysis were made, and the post-test evaluation was carried out.
As the shrinkage rate will change with the change of injection pressure, the cavity pressure of single cavity mould should be as consistent as possible, and the cavity pressure difference of multi-cavity mould should be very small. For single-chamber multi-gate or multi-chamber multi-gate cases, the same injection pressure must be used to make the chamber pressure consistent. Therefore, the position balance of... less

If we do not handle them properly, the service life of the combine chains will be greatly reduced. Therefore, I would like to remind everyone to pay more attention to the use of combine chains.
When transporting corrosive substances, the combine chains will inevitably contact with corrosive substances, and rust-like spots and rust on parts will easily affect the flexibility of chain hinges and rollers in reverse rotation. Stress corrosion and grain corrosion will also occur. The selection of raw materials for chain parts must be paid attention to for the combine chains to be used in the case that the transported materials contain corrosive substances.
After transporting corrosive substances using the combine chains, pay attention to cleaning in time, because if the combine chains and corrosive substances adhering to its surface are not cleaned in... less

Why is there a problem with the fastness of nylon fabric? In fact, the fastness of nylon fabric printing is affected by many factors such as the type of nylon fabric. Therefore, in the study of the fastness of waterproof nylon fabric, it is necessary to analyze the printing adaptability of different materials, select the most suitable ink and other materials, and pay attention to the operation technology to ensure the printing effect.

The production of Printing Pile Fabric https://www.warpknittedfabric.com/product/printing-fabric/ generally includes four processes: screen plate making (or cylinder engraving), color paste preparation, pattern printing and printing post-treatment.
Printing, like dyeing, makes dyes and fibers dye. The difference is that when dyeing, the fabric is fully and evenly dyed with dyes, while when printing, dyes of a certain color only dye certain parts of the fabric, thus causing the fabric to present patterns of various colors. In order to obtain various pattern patterns on the fabric and achieve the purpose of local dyeing, printing cannot be carried out in the dye liquor like dyeing, but the paste must be prepared into the original paste as the dye carrier, then the dye and necessary chemical additives are added to prepare printing paste and printing on the fabric, so as to overcome the... less

Enameled wires and electromagnetic wires mainly use insulating electrostatic powder coatings. Currently, they are mainly applied to insulated oxide film electromagnetic wires treated with concentrated sulfuric acid instead of metal aluminum wires, and can also be applied to enameled wires coated with insulating paint.
Since the coating thickness of ordinary powder coating is applicable to round wires with a diameter of 1.6mm or more or flat wires with a width x thickness of 1.6 mm x 1.6 mm or more and insulating coatings with a coating thickness of 40μm or more, it is not applicable when the thin coating is required. If the ultra-thin powder coating is used, the thickness of 20-40μ m can be achieved, but due to the high... less

2. Is to carefully check whether the aluminum composite panel surface color has different shades of color difference, color difference means that the quality is not pass. Of course, it is also possible to compare profiles of the same type together. Of course, if the color difference is too obvious, it is better not to buy them. Check whether the section thickness of the aluminum composite panel is the same as the marked model.
3. A smooth hard object can be used to scratch the surface of the aluminum composite panel, leaving a white scratch. The aluminum composite panel is gently wiped and observed by hand. If it cannot be wiped off, the material may have quality problems. However, if it can be easily wiped off, the oxide film thickness on the surface of the profile is qualified.

However, in practical application, TDS value often stays high in less than one year, which leads to premature failure of Ro System Component https://www.kokoelectric.com/product/ro-system-component/ for four reasons.
1. Pure water is not used for a long time.
Ro system component must be stored in humid conditions once immersed in water. Pure water will dry if it is not used for a long time (more than one month), and impurities filtered on it will solidify. When we reuse it, tap water cannot pass through. So even if we don't use water, we should always let the water purifier run. If you can't turn on the water purifier from time to time when going out of town, it is best to take out the components of the ro system and put them in disinfectant.
2. The local water quality is too poor, resulting in blockage of ro system... less

1. Tensile strength and yield strength
Different types of crate mould have a particular emphasis on the specific mechanical properties required for forging plastic crate mould materials. At the same time, the mechanical properties at room temperature should not be considered only while the more important performance indexes at actual working temperature should not be ignored. Do not pursue a comprehensive and high target that is blindly divorced from reality.
2. Impact toughness, section shrinkage and elongation
Since the choice of impact toughness index of forging crate mould material is closely related to the forging load property, if the impact toughness of forging crate mould material is low, the crate mould... less

Why wear and tear, and what methods are available to prevent wear and tear, and corresponding solutions are provided to everyone.
First point:
The wear of the industrial conveyor chain makes the chain ineffective. The main reasons are the poor material of the industrial conveyor chain and the improper operation of the workers. The most easily worn parts of the chain as a whole are sprocket and pin shaft. The wear of these two parts is mainly due to insufficient local lubrication, so in order to avoid this phenomenon, operators should pay attention to check the lubrication effect frequently, add lubricating oil in time, check whether there is abrasive in the lubricating oil or change the lubrication method. After the sprocket is slightly worn, the sprocket can be reversed so that the less worn side faces the chain.
