What is the name of the set?
<p>This article mainly describes <a href="https://www.dgmfmoldclamps.com/9-common-injection-molding-defects/">9 common injection molding defects</a> and the causes and solutions for these injection molding defects.</p> <p>During the <a href="https://www.dgmfmoldclamps.com/product-category/injection-mold-components/">injection molding</a> process, the gate stacks to the <a href="https://www.dgmfmoldclamps.com/product/sprue-bushing-type-a/">sprue bushing</a>, making it difficult to pull out. Opening the injection mold will crack and damage the product. In addition, the tip of the copper rod must be knocked out from the nozzle to loosen it, which greatly affects production efficiency.</p> <p>Since it is difficult to machine the tapered hole of the <a href="https://www.dgmfmoldclamps.com/product/small-gate-sprue-bushing/">sprue bush</a>, you need to use standard parts as much as possible, and if you need to machine it yourself, you need to make it yourself or purchase a special reamer. The taper hole needs to be polished to Ra0.4 or higher. In addition, you need to have a gate pull rod or gate eject.</p>
