In the world of high-precision plastic injection molding, the visibility of gate marks—the small scars left where molten plastic enters the mold cavity—can be the defining factor between a premium p...
Getting your part perfectly molded is only half the battle. The other half is getting it out of the mold without damage. A poorly designed ejection system can ruin a perfectly good part, cause mold da...
When a plastic part contains side holes, side undercuts, or protrusions that are not parallel to the mold opening direction, the corresponding mold components will obstruct part ejection after molding...
During cavity filling, the plastic melt must efficiently displace and remove two types of gases from the mold: 1) the air present in the runners and cavities, and 2) the low-molecular volatiles releas...
The gating system is one of the five core systems in plastic mold design. Its design directly impacts:Part layout and number of cavitiesMold base configurationInjection machine size selectionInjection...
High-speed injection molding demands specific design considerations to maximize efficiency and part quality. Generally, the resin used should exhibit high flowability and a high heat deflection temper...
When it comes to precision injection molding, the design of valve gates plays a critical role in ensuring product quality and manufacturing efficiency. Let's explore the essential design considera...
Wall ThicknessThe wall thickness of plastic parts has a big impact on their quality. If the wall is too thin, there will be a lot of resistance when it's being formed, and it'll be hard to fil...
Molding components refer to the mold parts that directly come into contact with plastic to form products, such as cavities, cores, sliding blocks, inserts, angle lifters, side core-pulls, etc. The mat...
(1) Plastic parts need a draft angle. When the mold opens, we need the plastic part to come out smoothly from the cavity and core. Without a draft angle, the part might stick to the mold, or get messe...
