   China mold products become increasingly large, and precision will be getting higher and higher. 10 years ago, precision mold precision is generally 5μm, now stands at 2 ~ 3μm.

   Soon, 1μm precision molds will be available. With the miniaturization of components and precision requirements increase, and some mold machining precision tolerance requires the following in the 1μm, which requires the development of super-finishing industry to further develop our multi-mold composite mold, a set of multi-functional addition to stamping die forming part , but also shoulder layers, tapping, riveting, and assembly tasks such as locking.

Through this multi-functional out of the mold is no longer produced bulk parts, but the bulk of the components, such as contact with the bearing components, a variety of small motors, electrical and instrumentation of the core components. Multi-color and multi-material plastic molding mold will also have rapid development. This reduces the production mold cycle, the future will be developed in different areas and applications.

   With the growing popularization and application of hot runner technology, hot runner molds in the plastic mold will gradually increase the proportion. Use of hot runner technology, the mold can improve productivity and quality of workpiece, and can greatly save workpieces of raw materials, the application of this technology has developed very rapidly in foreign countries has been very common.

Mold has also been internal heat production, some companies has reached about 30%, but, in general, the proportion is too low, yet to be developed. With the plastic molding process of continuous improvement and development of mold and adapt to the high-pressure gas-assisted injection molding process will follow the development of mold.

   Die proportion of die-casting mold industry will continue to increase. As the vehicles and lightweight motor and other products to develop in the direction of the die-casting mold numbers, the longevity and complexity of the ever-increasing demands will be presented. Along with the plastic on behalf of the steel, plastic and wooden parts of the development and product precision and complexity of the continuous improvement, the proportion of plastic mold will continue to improve its accuracy and complexity will also be along with a corresponding increase.

   Mold standard parts of the applications will be increasingly wide range of standard die and mold standard parts of the applications can significantly affect the mold manufacturing cycle. The use of mold standard parts can not only shorten the mold manufacturing cycle, but also to improve quality and reduce mold mold manufacturing costs. At the same time, rapid economic mold enjoy broad prospects. Because people asked mold production cycle as short as possible, so rapid economic development of mold has drawn increasing attention.

   Such as the development of various superplastic materials, to produce mold; use epoxy, polyester, or in which the filling of metal, glass and other materials to enhance production of simple mold. Such mold manufacturing process is simple, precision, easy to control, less shrinkage, low price, a higher life expectancy.

Can also be covered with cement, plastic mold making cars. ,The low melting point alloy mold, mold spray, electric molds, precision molds, stack mold, Plastic mold ceramic modeling and the use of light and heat curing rubber molds and other low-cost, rapid manufacturing will be further development of rapid economic mold. Fast Modular frame, quick-change red top will also be growing. Another use of computer control and mechanical hand-operated quick change die equipment, quick tryout plant technology will be developed and improved.

how to figure out how many parts fit in what size box?

Filed under: Plastic Injection Molding — Tags: , , — Rolf @ 2:57 am

For my work, we make small plastic parts. I am trying to see if there is a calculator online or a formula that I can use to calculate how many parts would fit into what size box.
For example, if a part weighs .5 ounces and it is 1″ by 2″ by 1/4″ thick, if I can’t have a box that weighs more than 40 pounds, what would be my choices of box dimensions.
Anyone know of a way to do this?

Organic plastic used for Audi composite parts
The front end of the new Audi A8 features organic plastic from Lanxess. Previously, in these kinds of applications, manufacturers used a steel or aluminium sheet, says Lanxess. In the Audi, an organic sheet, made with polyamide 6, is used alongside an aluminium sheet to make a hybrid front end.

Ordering Custom Injection Molding Parts

Filed under: Plastic Injection Molding — Tags: , , , — Rolf @ 11:22 pm

When you can’t find the plastic part you need for your design idea or invention, you’ll need to find a manufacturing engineer to build a custom injection molding part. You can either go about this by designing the part yourself and having a shop manufacture it, or contracting a shop of specialized manufacturing engineers to design and build the custom injection molding piece to your specifications.

If you’re area of expertise is in something other than engineering and custom injection molding, you’ll probably want to choose the later to ensure you get a part that works precisely. If you need to create a unique part, it’s necessary to find someone with the design and engineering expertise to take your concept and turn it into a finished part. Here you’ll find some points to consider when ordering custom injection molding parts to ensure that your part works exactly as you imagined and stands the test of time.

Understanding custom injection molding
Injection molding is the most common method of producing plastic parts. A engineer first builds a mold of the part in relief, which becomes the template for every successive manufactured part. The material is then poured into the mold, yielding a perfect part from the first piece to the 1,000,000th piece. With custom injection molding, once the mold is designed and crafted, the cost of producing subsequent parts is reduced dramatically.

How will the part be used?
In order to determine what type of material will be best suited for your custom part, the machine manufacturer will want to understand how the part will be used. Today there are more than 40,000 grades of resin available from which to make a custom injection molding part. The more information and documentation you can provide the machine engineer with the better. Prepare a document detailing the part’s functionality and provide a diagram of how it interacts with other pieces. Written documentation versus a verbal conversation leaves less room for interpretation.

Design concept
One of the greatest benefits of working with a manufacturing engineer is gaining access to years of design experience. The best way to communicate a design idea to an engineer is in terms of use cases, or how the end product will be used. This is a good exercise for you also, as it helps you to work through all the possible scenarios in which the piece may be used in order to shave off years of trial and error.

Considering “implied” uses
There are often numerous ways that a piece will be “used” other than its base purpose which will impact the design. Using a 2 liter soda container as an example, its main purpose is to store a carbonated beverage. However, because of its function, it’s likely to be dropped on kitchen floor so must be durable and built with a cap that won’t explode with increase pressure. It may also be taken to picnics so must be designed to handle exposure in hot sun or in melting ice without affecting the contents. The containers also must be shipped on large trucks so need to be able to remain stable in containers during shipping.

The right custom injection molding company should ask you lots of questions about your product so that they can truly bring the concept in your mind into reality. Providing the custom injection molding engineer with use cases, as well as some other visual influences, can help you achieve a superbly designed piece that exceeds your original expectations.
