Plastic precision Connector-overmolding. The determination of the structure of the precision plastic mold is the key, and the overall structure is the embodiment of the final effect of the product: the determination of the overall structure of the mold, the determination of the gate system, the determination of the ejection system and the determination of the water transportation system, and others should be conducive to the post-processing orientation of the product.

What about the feeding problem? First of all, we will choose a reasonable injection scheme according to the structure, weight, volume, and cost of the product, which can meet the requirements of customers as well as the requirements of quality. Second, we will design in strict accordance with the injection design standards: the layout of the runner should be uniform, especially the size of the cross load surface of the main and sub runner, the shape and size of the gate.

What about the ejection problem? Firstly, we will determine the ejection mode according to product orientation and structure. Secondly, we will evaluate the ejection balance and coexist with other systems, such as interference with water transportation and recycling marks, date clock, etc.

The design of the water channel system is based on four requirements the cooling line should be as balanced as possible.

High Precision Mold Manufacturing

The water cooling line shall not interfere with other mechanisms. Each water channel line shall be displayed with identification numbers or marks in and out. The accuracy of the mold cavity number or the accuracy of the parting line will directly affect the size of the product. Firstly, we need to make the manufacturing process plan and flow chart. Each completed manufacturing process must be fully inspected and the data inspection list must be recorded in the datasheet.

After the manufacturing is completed, the workpiece shall be processed and maintained. The design of the parting line of plastic mold is also an important part. If the design is not reasonable, the part is not easy to demouding or even damage the mold. Here are the design principles for the parting line of mold. It is convenient to eject out the plastic part and simplify the structure of the plastic mold.

After the demoulding direction is selected, the position of the parting line should make the plastic part fall done without any interference, like sliders, etc. For the plastic part with high coaxiality accuracy, the parting line should be selected at the position where two diameters can be placed on the lower mold or upper mold at the same time.

When the precision of the plastic part along the height direction is required to be high, the half overflow cavity should be used.

If the transverse flash is formed at the parting line, it is easy to ensure the height precision, while the non-overflow cavity is not easy to ensure. When the radial dimension accuracy is high, the influence of flash thickness on the accuracy of the plastic part should be considered, as shown in the figure. If the vertical parting of plastic parts is easy to ensure, the horizontal profile is difficult to control due to the thickness of the flash, which affects the accuracy of plastic parts.

Ensure the appearance of the plastic part, it shall be easy to clean the flash and not easy to damage the appearance.

The flash produced by the parting surface as shown in the figure shall be easy to clean and not easy to damage the appearance of the plastic part.We provide timely, high precision mold components to help to improve the efficiency of your injection molds and die casting.

Guide Pins.In the debate to determine the right number of cavities per mold, melt-rotation technology bolsters the case for high-cavitation molds. The last century's greatest advancement in injection molding was the advent of the reciprocating screw. This - along with further developments in equipment, process control, molding techniques and plastic materials - significantly improved the consistency of the melt delivered to the mold.

However, these advancements do nothing to address the cavity-to-cavity variations developed within a multi-cavity mold. It is now known that homogenous melt conditions and precise delivery of the melt to the mold are completely nullified by a branching runner. Could solving the mystery of the runner be the secret to molding high-precision parts in high-cavitation molds? In the past, parts molded of plastics were thought to be inferior to the parts produced from more traditional materials.

Discoveries and developments that improved processes, plastic materials and design have eroded this belief. In particular, the development of the reciprocating screw machine, advancements in screw design, process control and plastic material technology have significantly improved the consistency of the melt delivered from the molding machine.

But the consistency stops at the molding machine. As the molten material leaves the nozzle and enters into the mold's runner system, variations are developed in all multi-cavity molds - whether using hot or cold runners.

The true source of the variations was not understood. The result was that the industry accepted the resultant limitations and restricted itself to producing high-precision parts in molds with four or fewer cavities. But, as the reciprocating screw opened new opportunities for injection molding, the recognition of shear-induced imbalances - and recent melt rotation methods to address them - introduces new opportunities and leaves cause to reevaluate old traditions.

The study of polymer physics has led to discoveries that have isolated the primary cause of cavity-to-cavity variations. We now realize that product variations are resulting from significant inconsistencies in the melt entering the different cavities. A mold with perfectly duplicated cavities, fed by perfectly duplicated and geometrically balanced gates and runners, provided with perfectly uniform cooling and fed by perfectly homogenous melt will still produce parts with significant variations within a single shot.

high precision molds

The source of this problem is the development of high- and low-shear regions across a runner see Figure 1. Studies have shown that the shear-induced variation developed in a mold's runner system is the major cause of product variations in multi-cavity molds. The high-shear regions around the perimeter of a runner cause the melt in these outer laminates to be significantly hotter and have a much lower viscosity than the material laminates in the center of the flow channel.

When utilizing the traditional geometrically balanced runner, as the melt splits at the first runner branch, a side-to-side variation is created within the secondary runner see Figure 2. When the melt splits again at the next runner branch, this unevenly heated melt is sent to the downstream cavities at unequal temperatures, pressures and viscosities. The result is that all of the consistencies provided by the reciprocating screw, the process control, the perfect mold and the optimized plastic material are lost.

This causes the cavities to fill unevenly and will produce parts with different sizes, weights, cosmetics and mechanical properties. Prior to the recent mapping of actual melt flow conditions in a runner, it made sense to stick with numerous low-cavitation molds.

Using the common methods of attempting to balance flow - modifying gate or runner sizes, changing runner layout, blocking off cavities or adjusting drop temperature in hot runner systems - it made sense to limit the number of cavities in order to keep possible mold manipulations to a minimum.

Now that shear-induced variation has been exposed see MoldMaking Technology magazine, Exposing the Mold Gremlin, Part IMarchand Exposing the Mold Gremlin, Part IISeptember and virtually eliminated by means of melt-rotation technology see Figure 3the case for high cavitation has been strengthened and justifies reconsideration. More Mold, Less Variation In the January issue of MoldMaking Technology magazine, industry consultant John Bozzelli, principal of Injection Molding Solutions Midland, MIpresents a strong argument for the continued use of low cavitation, saying that the decision to jump to a higher cavitation mold cannot be based on the bottom line alone.

high precision molds

I agree with much of what he presents. However, the advantage of a well-designed and managed high-cavitation mold must not be discarded by the besieged U. In referencing some of my studies, Bozzelli indicates that one of the major problems of high-cavitation tooling is shear-induced imbalance. Some of these studies conducted at Penn State Erie, and published at ANTEC '98, conclude that 60 to 70 percent of product variation in multi-cavity molds is the result of shear imbalance, not variations in steel dimensions or mold cooling as we typically would think.

However, new melt rotation technology has proven to virtually eliminate these imbalances. The means of evaluating the source of variations in multi-cavity molds is fast and easy using the five-step process see MoldMaking Technology magazine, Exposing the Mold Gremlin, Part IISeptember We offer a wide range of mold technologies and options based on your part and development needs.

In addition to conventional single-face molds, NyproMold has extensive experience with complex high-cavitation mold technologies, including:.

Suitable for short runs of new part designs for initial testing and qualification, prototype molds can be completed in 2 to 6 weeks, depending on their complexity. Utilizing modular mold frames, NyproMold can rapidly build, test, and ship parts to your facility. Depending on your needs, you can purchase individual parts or the complete prototype mold. NyproMold blends product development needs with early production mold capability by using production-like gating, cooling, and ejection in the preproduction mold.

This allows for ongoing product and production capability development and optimization prior to production mold building. Pilot molds are built with some level of reusable components for integration into the production mold. Production molds are the culmination of the development process and are built based on the optimal design for the application. Designing and building high-quality production molds is the core of our business.

Once the design team completes the appropriate development steps, our manufacturing team uses an established step-by-step process and industry-leading CNC machining technology to build in quality.

This results in full interchangeability in mold components. Production molds range from one cavity to hundreds, depending on the application and production requirements.
