Solution To Weld Marks Of Injection Molding Defects

Weld mark formation mechanism Weld marks (also called water lines) are intersection marks formed when molten plastic flowing out of gates at different locations in the mold converges. The reason for the formation of weld marks is that the temperature, pressure, and speed of the molten material flowing out of each gate are not completely

Causes Of Injection Molding Defects And Floating Fibers

When the injection molding factory tested the mold before production, all the mechanisms were running basically normally, but the product had serious appearance quality problems, with radial white marks on the surface. And these white marks became more serious as the glass fiber content increased, This phenomenon is commonly known as “floating fiber”, which is

Injection Molding Parameter Settings In Mold

Prior confirmation and preliminary settings in mold Manual operating parameter correction Correction of semi-automatic operating parameters a. The molded products will not be whitened, cracked or deformed when they are ejected, clamped, trimmed and packaged. b. The mold temperature can be balanced and stable. Simple algorithm for cooling time of products with meat thickness of

How To Solve The Problem Of Silver Streaks Or Bubbles In Injection Molded Products

Silver Streaks Definition When plastics are disturbed by gas during the mold filling process, silver streaks or tiny bubbles often appear on the surface of the product or bubbles are formed in the thick wall of the product. The main source of these gases is that the raw materials contain moisture or volatile substances or

Reasonable Setting Method For Injection Molding Pressure Holding

In the process of studying the injection molding of plastic products, injection molding is often divided into two stages: in the first stage, most of the plastic is filled into the mold, generally 90% to 99.9% of the entire product volume; in the second stage, the pressure The actual product is obtained with the same
