Gate is also known as Gate Location. It refers to where the plastic enters into the cavity of the injection mold. The "white marks"showed on the above photos are called Gate Vestage, which were left by the cold runners. They are usually trimmed manually or cut off automatically by injection machines.
Calculate melt residence time by formula in molding guides . If >5 minutes, use smaller shot machine or reduce cycle time . Melt temperature too high Measure and reduce melt temperature . Cracking when mold opens • Overpacking • Hot mold • Poor drying • Breakaway too fast • Needs vacuum break • Reduce either packing pressure or time .

Thin Wall Molding. Thin wall molding is a specialized form of conventional injection molding that focuses on mass-producing plastic parts that are thin and light, without structural compromise, in order to achieve material cost savings and shorter cycle times. Faster cycle times improve productivity and lead to lower costs per part.

Injection Molding Reference Guide SECOND EDITION compliments of: Injection Molding During 1st stage injection an insufficient shot size or a low injection speed may cause sinks and voids to form. High injection speeds will also create excessive shear at the gate area and jetting may occur.
Midstate Mold explains the basics of injection mold gates. While injection molds tools are hard to design and manufacture, their core concepts are easy to understand. The mold itself consists of two faces, between which is the cavity and core set into which the plastic is injected.
Mold Design. Injection molds must be properly designed to ensure quality plastic components. Mold design impacts productivity and profitability of your molding operation. This section offers guidelines for designing an efficient injection mold.
Oct 12, 2019 · calculate the exact gate and runner during mold design. Calculating the runner size. The runner is part of the injection molding unit of a plastic mold manufacturers factory which connects the sprue and the gate. It is a cavity-like portion which holds the liquid plastic before it passes through the gate and fills the mold in the right way.

Nov 17, 2020 · A great solution would be to reach out to the molding facility and find one that makes a part somewhat similar in size, shape and wall thickness to your part. For a small fee the molder will shoot your desired resin into the mold and then use the parts to calculate a precise shrinkage for your material in a similar profile to your product.

Aug 12, 2018 · The style and quantity of gate and feed style often determine the specifications of plastic mold base. Whether the design of the gate system is reasonable will directly affect the appearance, internal quality, dimension precision and molding cycle of the molded plastic parts. Concept and classification of feed system This exceeds the 40000 rate for the material, slow the fill rate and open gate to cure: Shear rate=32 x 33.02 / (3.14159 x 2 x 0.1653) = 37437 The gate has been increased to 1.65 mm (0.165 cm) and the fill time to 2 seconds. Anything less than this will take the shear rate over the limit.

For plastic injection mold design, one of the most important factors is how and where the gate should be located. As the mold opening, the gate It serves as the boundary between the part and the scrap, so its location, size, and shape play an important role in how everything should be constructed, from...The heated plastic is injected into the mold. As the melt enters the mold, the displaced air escapes through vents in the injection pins and along the parting line. Runner, gate and vent design are important to insure the mold is properly filled.
