How to solve common defects in thin-walled injection molded parts
Lower mold temperature and enlarge gate: optimize molding conditions to ensure stable size of plastic parts.
In order to solve common defects in thin-walled injection molded parts, the following measures can be taken: To deal with the problem of short injection, the injection rate needs to be increased to ensure that the melt fills the cavity before the condensation layer is formed. For thin-walled plastic parts, the reduction in the flow-to-thickness ratio (L/T) makes this requirement more stringent. Conventional technology may be difficult to meet in this situation, requiring injection molding machines with high injection rates.
The common defects and corresponding faults in the injection molding process of polypropylene (PP) are analyzed and eliminated as follows: Inadequate injection process conditions are not properly controlled: Process parameters need to be appropriately adjusted. Insufficient injection capacity of the injection molding machine: When the injection capacity of the injection molding machine is less than the weight of the plastic part, a larger injection molding machine should be replaced. Small cross-section of runner and gate: Increase the cross-section size of runner and gate appropriately.

Got it! Your mouse was corroded by something containing solvents. The outside of your mouse is the kind with a rubber coating. Pure engineering plastic is very stable. There are many solvents at home. The oil from eating and the sweat from your palms can also corrode rubber, and soft rubbers can also corrode hard polyester plates (such as glass ruler).
In my experience, it is not broken. The transparent thing in the groove is the reflector of the optical mouse. It is normal for it to be a little loose.
How does Gucci distinguish between true and false?
Look at the LOGO letter weave. The authentic Gucci's double GLOGO pattern weave is very neat, and the pattern of the two capital letters G can be clearly seen. The fake Gucci double Glogo pattern does not look like a clear capital letter G, but like a C; and the authentic double G is separated and will not be connected together.
To identify the authenticity of Gucci men's shoes, you can check them one by one from the seven dimensions: shoe box, sole, insole, body details, shoe logo, hardware accessories, purchase certificate and after-sales sales.
Dear, if your Gucci bag says made in italy, it's intentional, because Gucci's official logo is all lower-case made in italy. Whether it is a genuine product or a replica, this logo should be clearly visible.
First of all, you can log in to Gucci's official website and use the "search" function to enter the number on the watch. If the number cannot be found, it may be a fake watch. Secondly, the double G logo pattern on the authentic Gucci watch is clear and separated, rather than connected or blurred. The authentic hands are long and have various shapes. The English printing is accurate and free of typos. The trademark writing of the authentic dial and back cover is clear and complete, the watch glass is smooth and clear, and the coating has no bubbles.
