Injection Mold Design of Gates

by:Yougo      2020-08-12
Every injection mold has to have a gate or an opening through which the molten plastic is injected into the cavity of the mold. The type and size of gate plays a very significant role in the process of plastic mold and must not be overlooked. In the custom injection molding business, margins are extremely tight. This requires the mold maker to make a very accurate determination of the size and type of gate for the injection mold. The wrong gate can spell disaster, or at least reworking the mold, which can quickly eat up profits. There must be gazillion plastic parts in the world: cell phones, computers, hula hoops, keyboards, TVs, toy machine guns, goggles, etc, etc. Gates vary in size and shape depending upon the type of plastic being molded and the size and shape of the part as well. Obviously, larger parts require larger gates, or even several gates. The tab gate is the simplest of all. It is the type of gate you see when you buy a plastic product that requires breaking from the runner, or tree-like piece of plastic attached to the part. It is usually a flat, tab-like connector that enables the plastic to flow into the part. A tunnel, or submarine gate, is more complicated and requires a much higher degree of skill to add to the mold. This type of gate is a cone that is added below the surface of the part, thus the name: submarine gate. It also has the appearance of a tunnel. This is used when there cannot be much evidence of the gate left on the part. This is known as gate vestige. It is also used in high production molds where everything is automated and the part must break free from the gate in order to be separated and packaged. The smiley gate is so-called because when you look at it, it resembles a smile, sort of. This is more difficult to machine and is used to add a gate right at the bottom of a plastic part. It is like a tunnel gate, except the bottom portion is cut off, or truncated. This enables the gate to be right at the bottom of the plastic part. Smiley gates are also used in high production applications where the part must break free from the gate for purposes of automation. The banana gate is quite a novelty, but very useful. These gates are used when there can be no trace of the gate on the plastic part. It is like a tunnel gate, but curved, like a banana, so it can reach underneath the part and allow the plastic mold to be injected into a hidden area of the part.

However, custom mould isn't the only producer in domestic, and many people feel that Taizhou Huangyan Yougo Mould & Plastic Co., Ltd's service leaves much to be desired in terms of functionality and design.
Taizhou Huangyan Yougo Mould & Plastic Co., Ltd’s purpose is to create superior value for our customers, employees, communities and investors through the production, conversion, delivery and sale of energy and energy services.
What Taizhou Huangyan Yougo Mould & Plastic Co., Ltd discovered was that innovation occurs when business models match up with one or more of the custom mould where technological advances overlap with market needs, thus resulting in growth and transformation.
Making a few technical tweaks to the way you structure and distribute custom mould could be the difference between an engaging, thought-provoking product and a perfunctory one.
Obviously, financial return is important in manufacturing custom mould, but I think that's not enough. I think many customers want to support something they really believe in.
