Gates will directly influence the end results of the Injection plastic mold process. We already mentioned what happens when the gates are too big or too small. The gate size is also directly related to timing. You need to make sure the plastic can reach all areas of the mold before it starts to cool. If your timing is off, the plastic could start to harden in certain parts of the mold too soon....

Two of the major disadvantages to Injection plastic mold are the high tooling costs and large required lead times. Tooling is almost a project in and of itself and only one phase of the entire injection molding process. Before you can produce an injection molded part you first have to design and prototype a part (probably via CNC or 3D printing), then you have to design and prototype a mold...

The determining factors in the cost of your Injection plastic mold are a combination of the part size, complexity, material, and anticipated quantities. For instance, if you wanted 1,000 washers per year, we would recommend a single cavity mold, meaning it makes one washer per machine cycle. In that case, the mold would probably be $1,000-2,000. However, needing 100,000 Xbox controllers every...

There are several factors that will determine your Injection plastic mold cost, including: Part sizeComplexityMaterialQuantities Material selection is another consideration in determining the cost of injection molded plastic parts. In general, the plastic used to create the product is determined by what the product will be used for. Different plastic materials have different properties and an...

Jinhong uses Straight ejector pin, and their placement depends on a number of factors. Obviously the shape of the part is one (see example in illustration). Factors like draft and texture of sidewalls and depth of walls and ribs can increase the likelihood that areas of the part will cling to the mold. Resin choice can also affect pin placement or size. Some resins are "stickier," requiring...

In fact, when choosing a commodity Injection plastic mold manufacturer, Jinmatai reminds everyone to pay attention to the market first to see if there are many mold manufacturers in the market, and what kind of commodity mold manufacturers produce mold products that are easier to use. There are actually several different inspection indicators. Comprehensive strength of mold manufacturers...

The use of hot runner systems in Injection plastic mold has been possible for nearly 50 years, but it’s only since the late 1990s that the use of a hot runner system surpassed cold runner systems in plastic injection molding. Hot Runner and Cold Runner SystemsIn a hot runner system, a manifold system heats the mold tool and sends melted plastic to nozzles which deliver the plastic to...

As you begin work on developing your next product or enhancements to an existing one, here are nine DFM principles you should follow: Minimize the number of components on Injection plastic mold. The more seams or connections a finished part has, the more places it has to fail. Simple parts with fewer elements are more reliable, easier to assemble, and they are also subject to fewer inventory...

To understand how Injection plastic mold can really help today’s manufacturers, here are the top 10 benefits to utilizing the process (in no particular order): ABILITY TO PRODUCE DETAIL/COMPLEX GEOMETRYWith the right tool design and a scientific molding approach to process optimization, injection molding can help manufacturers produce highly complex, detailed plastic parts, such as the...

Working temperature of Straight ejector pin is crucial because it affects the lifetime or durability of an ejector pin. For example, if the working temperature is high and the ejector pin being used is made for a low working temperature environment, then the ejector pins will certainly not last long. In the market, there are three common types of ejector pins: (1) through hard pins, (2) nitride...
