Finally, he was convinced to try a hot sprue bushing and immediately saw significant savings on material by direct gating the hot sprue to the part. In addition, the gate location changed from the periphery to a central location on top of the part. As a result, he could reduce his cycle time from 21 seconds to 15 seconds and no longer needed the secondary operations because of the more balanced gate location, freeing up manpower for other work.

Moldmakers and molders who use hot runner systems in their molds will be the first to disclose that it is often the most expensive part of the mold build. But they quickly add that it is worth the investment based on reduced cycle time, resin cost, elimination of post-processing, product lifecycle, etc. Meanwhile, hot runner holdouts are skeptical, wondering why they should add thousands of dollars to the upfront cost of a mold when the cold runner system gets the job done. So, let’s examine the facts.

In the early days of injection molding, cold runners were the only method for delivering plastic to a mold that ran more than one part. It is a method still used today. Cold runners usually comprise two or three plates, and a nozzle delivers the molten plastic into the mold via a sprue, then through channels or runners that lead to the mold cavities that are then filled to make plastic parts. Typically, the sprue requires the most time to cool because it is usually thicker than the runners and parts.

Steps to improve data-driven decision-making and key features of a cloud-based system for mold monitoring and asset management.

Molders then must perform secondary operations, which begin with trimming gates, if necessary. Dealing with the runners and sprue requires the molder to perform post-molding operations such as regrinding and pelletizing, then mixing with virgin plastic, if the reuse of plastic is permitted. Unfortunately, many engineering and medical applications do not permit regrind reuse or only allow a small percentage. Any remaining scrap plastic must be disposed of or sold for pennies on the dollar.

Topping the list of plastic mold manufacturers in China is Seaskymedical, a medical plastic manufacturer. It is not a surprise that the company sits on top the list because they provide one-stop injection molding solutions to their clients worldwide. Services they offer include mold design, mold manufacturing, material selection, injection molding, and product development.

Another benefit is there is no apparent vestige. The valve gate makes a clean break from the part, leaving only a fine witness line from the valve gate pin. This makes the valve gate system a great option for cosmetic parts that are decorative, as well as for medical applications where gate vestige is not allowed.

To illustrate further, a long-time molder ran a single-cavity mold using a cold sprue with a branch of a runner to make little nylon wheels. The customer ran 21 seconds to fill each part and scrapped the sprue and runner with every cycle. Then he would machine each wheel because he worried it wasn’t truly round, adding yet another step to the production process.

What exactly does a hot runner do? If you’ve been in the injection molding industry for any length of time, you might think the answer is obvious, but it is not.

Costs are determined based on the hot runner requirements. A single-cavity mold will typically require a hot sprue bushing and those calculations are straightforward. However, when the mold has more than one cavity, there are a few factors to consider.

There is no doubt about it: More and more molds are being designed to include hot runner systems or hot sprue bushings. For those who build and run hot runner molds, it is not hard to see the reasons why. While expensive to build, hot runner molds can be more economical in the long run than their cold runner counterparts. Still, there are many hot runner holdouts, so it is time to build the case for transitioning from cold to hot runner molds.

The first step to switch over to a hot runner mold is to perform a design analysis to ensure that a hot runner is appropriate for the application. For example, determine if the material being molded is suitable for a hot runner design, which is an essential consideration whether the mold is new or being retrofitted. Though most resins are amenable to hot runner usage, there are exceptions. Consult your material supplier for their recommendations. If a hot runner system is deemed feasible, determine whether to go with a thermal gate or valve gate system. This is a good time to seek input from a knowledgeable hot runner supplier who can recommend suitable options. Most hot runner suppliers also offer Moldflow analyses to ensure the hot runner system is balanced and to assist with a part fill study.

A water-based, eco-friendly plastic mold cleaning system helps Rankine-Hinman Manufacturing restore flow rates and avoid big-ticket failures on complex and costly molds.

Valve gate systems use either pneumatic, hydraulic cylinders or servo drives to actuate a valve gate pin to control the flow of plastic into a cavity, giving the molder more control over the molding process. Several advantages can be gained by using a valve gate system, including enlarging the gates to fill the part faster, decreasing cycle times.

Released earlier, this video remains a valuable recruitment tool and is being re-promoted in celebration of Manufacturing Day 2024.

Xiamen supplies metal and plastic products and also specializes in the production of parts and finishing with several factories dedicated to plastic injection molding, die casting, etc.

All successful mold build projects start with examining the part to be molded to ensure it is moldable and will meet the customers' production objectives.

Thermal gate systems are the most common and economical. Thermal describes the type of shut-off used to stop the flow of plastic into the mold cavity. The small gate freezes as the part cools and stops the plastic flow so that the part can be ejected. If the gate is too big, the thermal seal will fail, causing stringing or drooling.

Cold runner molds do have their advantages. They are simple in design, relatively inexpensive to build and easy to maintain. However, hot runner molds have proven to be a much better alternative for most applications.

Injection molding is a technique, or a manufacturing process used for producing molded items, that is, parts of a material in larger volumes. This is done by having plastic materials that have been heated to a molten state injected into a mold, cooling them down, and then leaving them to harden. Thermosetting and thermoplastic polymers are the most commonly used materials when it comes to introduction of the injection molding process.

A focus on electrode design and automation helps toolroom improve efficiency, reduce tooling costs and deliver higher quality products.
