The Injection Mold is nothing More Than a Heat Exchanger, and if the cooling elements are not properly featured, you will have untold processing issues. For years (at least in US) the standard for water channels was to use 7/16" dia bores. This standard size was selected for a variety of reasons and mainly to agree with the hardware sizes that have been used for connectors commonly available. The size of these water channels is not as important as the placement/positioning within the Core/Cavity blocks. Most times it is difficult to position them in the desired position due to Ejector Pins and other Moving Elements within the tool. The type of Water System used at the Molding Facility also has a significant effect on the efficiency of how your tool runs.....Are Chillers used? Tower Chiller? There are certainly many elements to validate when it comes to Cooling. PFMOLD. When considering the secondary mold function, ie that of a heat exchanger it is not achieving uniform temperature across the injection mould which is important. The amount of heat energy absorbed by the mould varies dependent on the flow of material through the cavity. Around feed points there will be maximum heat generated due to material flow and shear. At the end of fill the material temperature will have reduced and the surface of the injection mold will absorb less heat energy. Physical restrictions which restrict size of cooling channels such as small inserts, deep sections, etc have to be considered in each case. Also don't forget that whatever size your cooling channels, when you come to connect them to supply and return pipes you will have a reduction in area, due to the need to fit connectors. There are many factors on which the diameter of the mold cooling channels depends, some are listed below: To cool the hotter section of the component in the mold. The cross section of the component has to be checked and the one with a greater area should be balanced or forcibly solidified To maintain injection mold temperature uniformity in the molding area. Sometimes hot oil circulation is also used to heat the mold to certain temperature or maintain the mold at a certain temperature. The type of plastic plays a very important role in deciding the diameter of the cooling channels. The mold design requirement is also a criterion (what is the quantity expected from a single mold). The above will help us decide whether cooling is required and the diameter of the cooling pipes. Search Google for Injection Mold Design handbooks. Many have calculations for channel size. Size of channel also determines how close the channels should be to the part. Too large dia, too closely spaced, and too close and the mold steel will move under molding pressure. Pump G/Minute, number of circuits, diameter of channels, number of 90 degree bends in circuits, etc. All these need to be review for optimum water flow, pressure losses, heat removal etc.

The injection mold is the tool to form the plastic into designed shape and measurement, it makes massive production in our time much more economical and efficiency, it was called the mother of industrial. You can't imagine how ordinary people afford a car if the components are made by bare hand. Look around wherever you are now, you see a lots of things made in plastics. They are all come out of injection molds. Basically, molds consist of 2 main parts: the cavity and core, the cavity side forms the major external surface, core side forms the external features of the molded part, during molding processing; the core and cavity will be separated so the part can be removed. Ideally the part can be molded by the cavity and core directly. But in a lot of occasion, besides the cavity and core, it requires complicated mechanisms when the molded objective is complex, mainly it's because the parts cannot be released completely by 2 directions, it was called undercut, which can't be released by the core and cavity directly, there are lifters and sliders, a series mechanisms are design to release the undercuts, so any success of injection mold depends heavily on the design. An injection mold is a precision tool and also must be strong enough to withstand thousands of high pressure molding cycles, so the material of the injection mold must be carefully; it's normally special and expensive steel, The way of manufacturing injection mold have been changed along with modern technology developing, main steps are CNC milling, drilling, EDM, wire-cutting, CAD/CAE/CAM technology utilized in a wide range make the lead-time of mold making shorter and shorter.

Tool longevity is just as important to part cost and quality as the design and build. Regular, careful maintenance can prevent part failures and lower the overall cost of your injection molding program. What is mold maintenance? Mold maintenance, or tool maintenance, refers to the cleaning and repairs that are needed to keep an injection mold in the best working order. Maintenance is performed routinely over the life of the mold (preventative maintenance or PM), and also when any problems arise. Why is mold maintenance important? Many buyers overlook mold maintenance when choosing a supplier, but it`s actually a critical aspect of a successful long-term molding program. The condition of the injection mold affects the quality of the plastic components produced. Performing necessary preventative maintenance improves tool longevity and part quality by stopping issues before they happen. What problems does mold neglect cause? Over time, the molding process can cause wear on a mold. For example, a fine layer of material gradually builds up on the mold surfaces; if left unchecked, this vent deposit can dent the tool, causing flash and other unwanted part. It`s like owning a car. If you never perform regular maintenance, like changing the oil, the mechanical parts will experience wear, reduce running efficiency, and eventually fail. Unfortunately, many molders will avoid doing maintenance until these quality problems arise or the tool breaks down. Repairing the mold at this point can be expensive and can jeopardize your part supply. However, if done regularly and correctly, preventative maintenance can improve production and lower the overall cost of owning the tool. What are the benefits of a properly maintained mold? A well maintained (and designed) mold is key to producing consistent, high quality injection molded parts. Uniform cooling throughout the cavity impression (and from cavity to cavity in multi-cavity tools) will yield the highest quality part and the fastest cycle time. Ensuring a quality mold requires well-designed tooling and higher precision build, both of which can increase the tool construction cost and regular maintenance cost. However, these measures will ultimately save you significant costs on repairs. As a best practice, choose a molder that performs maintenance, such as cleaning parting lines during the production run, and has a dedicated service team that documents and tracks mold maintenance, to ensure that your tooling gets the long-term care it needs. How can your supplier help? Working with your supplier as a strategic partner can help reduce many of the risks and costs associated with injection molding. They can help you: Optimize part design and mold design The complexity of the part design drives the tool design. Working with your supplier to optimize both part design and mold design can improve the longevity of the tool and the quality of the part. Often simple feature changes can improve the robustness of the tool, simplify manufacturing, and ensure consistent part quality. Make the most of your tooling investment Achieving the [right size" for tooling budgets means optimizing the tooling investment for the type of part and volume required. Over-investing wastes money, but under-investing results in a shorter mold lifespan, supplier reliability issues, and added costs. Added expenses can include reactive tool maintenance while the tool should be producing parts, as well as overall mold maintenance and repair over the life of the tool. PFMOLD designs molds to make the PM process easier on the customer. We establish a unique PM cycle for every mold depending on the specific part design, industry, material, and other factors. By providing multi-level maintenance-ranging from a basic cleaning and wear assessment to a higher level teardown with a complete inspection-on a scheduled rotation that is fully documented at each service interval, we can ensure that your mold functions properly each time it is put to use. Choose the right development tools There are many options for making prototype parts. SLA, take-apart tools and other strategies can accelerate a project`s time to market. For specific applications such as high-cavitation precision parts with complex tools, a production intent prototype mold that replicates cooling, gating, and ejection strategies will lower the risks associated with production molds. PFMOLD also builds components so that they can be removed individually without having to disassemble the whole tool, which saves maintenance time and improves tool longevity.

Guide Pins– fixed to one half of the mould and align the two halves by entering the holes in the other half. Runner– passageways in the mould connecting the cavities to the sprue bush. Gate– Frequently the runner narrows as it enters the mould cavity. This is called a gate and produces a weak point enabling the moulding to be easily broken or cut from the runner. Sprue Bush– Tapered hole in the centre of the mould into which the molten plastic is first injected. Locating Ring– Positions the mould on the fixed platen so that the injection nozzle lines up with the sprue bush. Mould Cavity– The space in the mould shaped to produce the finished component(s). Ejector Pins– These pins push the moulding and sprue/runner out of the mould. The Shot– Total amount of plastic injected into mould. Sprue– Material which sets in the sprue bush.
