1,000th ‘Power User’ Achieves Certification in SolidWorks Program

SolidWorks Corp. has reached a milestone in its international program to recognize the most proficient users of its 3D mechanical design software by designating the 1,000th Certified SolidWorks Professional (CSWP). The CSWP program makes it easier for design engineers to market themselves and their services, and helps employers identify individuals who excel at quickly designing sophisticated products.

Stephen Borg, CEO of Acorn Technical Services of Oak, Nebraska, USA, is the 1,000th CSWP. Certification helps him assure new customers that he is qualified in 3D mechanical design with SolidWorks.

“CSWP certification really means something,” Borg says. “Only skilled and proficient engineers even attempt the exam. So when we tell new customers we know SolidWorks, they don’t have to worry about our skills. And if I’m hiring a CSWP engineer, I can be confident that he or she is proficient with SolidWorks.”

Although challenging to obtain, CSWP certifications have doubled every year since the exam’s inception. Many software vendors offer certifications based on the results of a question-and-answer exam, but SolidWorks also requires a hands-on demonstration of modeling skills. Candidates must show that they have advanced skills in building parametric solid models and can adhere to evaluation criteria for accurate design specifications. By the end of the eight-hour exam, they will have modeled a minimum of six challenging parts, assemblies, and drawings.

“Design engineers who are proficient enough to become CSWPs become part of a special community of proven SolidWorks talent and solid modeling innovators,” said Jeremy Luchini, SolidWorks certification program manager. “SolidWorks is especially attentive to their feedback on our products, and their suggestions often show up in the next product release. We’re proud of the success of this program, which is challenging enough to be meaningful and accessible enough to be achievable.”

CSWPs receive event discounts, business card logos, SolidWorks active wear, and a listing on the Solidworks website. Information on the CSWP program is available on line.

American Mold Builders Report Shows Importance of Injection Molding in Ireland

Applied Market Information Ltd.‘s latest guide to the injection molding industry in Ireland shows plastics processing as the most important component of the plastics industry in that country. Last year it consumed an estimated 26% of all polymers. Injection molding is now substantially greater, by volume of material used, than either pipe or film extrusion.

As outlined in AMI’s Guide to the Injection Molding Industry in Ireland, the strength of Ireland’s injection molding sector is due the country’s success in attracting foreign investment in advanced manufacturing industries over the past two decades. Since 1980, 40% of American investment in European electronics has come to Ireland, and over 300 overseas electronic companies operate there. Some 80 medical device companies operate in Ireland, including 10 of the world’s top 15 device companies.

Many of these companies have their own molding shops, but there is also a substantial subsupply sector to support these foreign-owned enterprises. Of the 154 companies listed in AMI’s guide, 50% are in-house. Over 60% of all injection molders in Ireland are owned by a foreign parent, with American companies the largest investors, followed by German businesses.

A downturn in demand for IT and computer products in 2001 did have an impact on the injection molding industry with several companies shutting down in 2002. However, the medical devices industry remained a strong sector.

For 2002, AMI estimates that consumption of polymers by the injection molding sector amounted to 63,000 metric tons. After a disappointing 2001, demand rose by 3% over the previous year, in line with the average trends for a five-year period from 1997. AMI forecasts that for the next five years, demand will increase on average by 2% per year, which would result in an injection molding sector of about 70,000 metric tons by 2007.

The main challenge facing the industry is its reliance on foreign-owned OEMs with their global manufacturing capabilities.

  3. Mold fitting and assembling the mold. Up to this step, the most important job has been done. A mold has been made.
  4. Mold trial process: Introduction of the plastic material in the heated chamber. The plastic material is mainly in the form of pellets which are liquefied by the high temperatures in the chamber.
  5. The liquefied material is allowed to flow into the mold that is used to make the plastic molding parts. It is commonly referred to as the shot.
  6. The material is allowed to cool and solidify while in the injection mold. Temperature can be regulated by using of cold water pipes or oil pipes. This is to cool or lower the temperatures to facilitate faster cooling of the molds.
  7. The plastic molding parts are then forced out of the mould once they fully solidify, the mold closes and the process is repeated, this repeated processing we called massive production.

The future of plastic molding

  Plastic molding is advancing over the years. The thinnest materials that the first injection molding machine could make were about 2.5 mm and the capacities of the discs was less than 1 GB. With advancement in technology, molds being made today can be as thin as 0.5 mm and can

hold 20 GB. Today, many molding companies are specializing in the production of particular parts in order to increase the quality of molds being produced. The increased number of companies in the business of plastic molding are increasing. This is expected to result in a drop in the prices of plastic molds in the future.

Structural Foam Molding

Structural Foam Molding

Compare to plastic molds and die casting, Structural foam molding is total different type of mold

Structural foam molding is known as the low-pressure technique for processing thermoplastics. The molding cavity is filled by the foam from bubbles which is created by the inert gas such as nitrogen which is inserted to the resin. Another process of creating foam is through the gases which are created by the chemical blowing agent. This process is able to create the rigid parts with solid surface.
The common understanding of the foam molding process uses high density polyethylene (HDPE). In fact, instead of using HDPE, this process also uses plastics including polyethylene (PE), polypropylene (PP), and also acrylonitrile butadiene styrene (ABDE).

The main issue is that this process needs low pressure. When the resin flows in the mold, the surface cells will burst to create skins for thicker and more durable walls of the final products. Before the resin come into the mold, the foaming agent is held by an injection screw. Then, the foam which is produced by the inert gases will be inserted to the molten resin so that it will flow further.

Plastic Mold

Plasti mold

By using structural foam molding, there are some advantages which the manufacturer can take including lower setup cost. Since this process needs lower pressure, the equipment which is needed is economically produced which can result larger parts. In addition, lower internal pressure will also contribute to heavier cellular structure so that the final product will be sturdier.

Commonly, resins are inserted into the mold at 500 degree F and cooled at 100 or 140 degrees F. It can cause the piece to set. In-mold shrinkage can possibly happen. However, it depends on some factors such as type and size of the machine and the thickness of the mold. The structural foam is able to shrink immediately after it is released from the mold. It is commonly able to shrink from 1.5 up to 4 percent of the original size. Commonly, structural foam part can be used in the place of concrete, wood, metal, and also fiberglass.

Plastic Injection Molding

Plastic Injection Molding

About 2 years ago I purchased a Tool set. It came with a wonderful set of tools, but a really low end, thin and hollow plastic injection molded case that belies the namesake and tradition. Needless to say, the case finally gave up the ghost this past week. I began shopping for a replacement tool box easy for the old set that has since grown to over 200 pieces. Wanting some level of organization that is needed on the trail while off roading, the plastic tool box intrigued me due to it’s thick plastic construction and it’s similarity to a larger tool chest with extendable drawers. Its size and depth allowed me to place it in the same spot as where I held the old plastic injection molded case in my truck.

Plastic Injection molding is preferred for producing complex shapes of various sizes having very fine details. The parts produced by using this method have greater dimensional control. Plastic Injection molding is used for producing parts in large quantities. Plastic molding is widely used for many applications. When you design parts for plastic injection molding, you can arrange multiple pieces in one mold by connecting them with small bars ~0.1″, however the sub-components must not have widely varying volumes. When the design does not allow for additional structures to improve strength, consider using a stronger material, such as glass fiber filled plastic. Consider specifying a fire retardant material when necessary.

Nowadays, liquid injection molding is becoming increasingly important. One reason for this is the increased performance requirements of the finished rubber parts. In addition, more and more producers of rubber parts are seeing the benefits in crown the high level of automation and productivity. Injection molding technology, using liquid rubber, combines the speed, cost efficiency, and versatility of plastic injection molding with the outstanding properties of silicone rubber. It is used in many applications where organic rubber cannot perform, such as military, aerospace, automotive, healthcare applications, etc. The use of silicone rubber combines the properties of resilience, high temperature stability and inertness as silicone is generally unaffected by temperatures from 100 degrees Fahrenheit to 450 degrees Fahrenheit. Progress in liquid injection molding technology has made faster cures possible, enabling unit cost reductions.

The Plastic injection molding machine has two parts: the injection unit which melts the plastic and injects the plastic molding into the mold, and the clamping unit easy which holds the mold. The injection molding unit clamps the mold in a closed position during injection, opens the mold after cooling, and ejects the finished part. Injection molding’s efficiency varies by the number of parts you plan to produce. For a small quantity, such as 10 parts, it may be less expensive to simply machine the desired part utilizing a milling machine. On the other hand, if you desire several thousand parts, injection molding is ideal. When you submit your order for an injection molding parts, the websites will assign staff to help evaluate the most appropriate mold material which will vary by part tolerance and number of units anticipated.

Over Molding

Overmolding and over molding

Over-mold injection molding , th eprocess is the same as insert molding, where an existing component is loaded into a mold and plastic is molded around it to create a multi-material single part. Insert-molding is most synonymous with combining metal components with plastic in such products as electrical pin connectors. When the term over-molding is used, the metal component is simply replaced with a previously molded plastic part. Single-shot injection molding machines are used to produce both the plastic component and the over-molded plastic. Tooling for injection over-mold injection molding requires two molds; one for the plastic component and one for the over-mold. Over-mold injection molding requires labor to handle the plastic component and load it into the second mold. Over-molding is generally reserved for higher priced parts that can absorb higher machine time and labor costs.

If you are planning to go into a plastic molding business, you should first know the different processes. Choose from a plastic molding process that fits your budget, your expertise, and your resources. In Injection Molding, melted plastic is forced into a mold cavity. Once cooled, the mold can be removed. This plastic molding process is commonly used in mass-production or prototyping of a product. Injection molding machines were made in the 1930’s. This can be used to mass produce toys, kitchen utensils, bottle caps, and cell phone stands to name a few. Plastic molding is a very technical process. It needs experts in this type of manufacturing business for it to be competitive in the market. Therefore, a very scientific and systematic study should be first made before going into this endeavor.

plastic molding | Plastic injection mold

Injection molding is an effective way to make custom parts. Granules of plastic are melted down and then injected into a metal mold; there the molten plastic hardens into a designated shape. Then you open the mold and a new part is removed, inspected and is ready to go. Injection molding is an incredibly versatile form of molding plastics. As with everything, injection molding has its ups and down so it is important that the ends justify the means for your project needs. There are three main components in the injection molding process. The injection apparatus itself which melts and then transmits the plastic, the mold, which is custom designed, and clamping to provide controlled pressure.

Thermoplastic injection molding is molding the most widely used of all plastic processing methods. The injection molding machine reduces pelletized raw material and colorants into a hot liquid. This “melt” is forced into a cooled mold under tremendous pressure. After the material solidifies, the mold is unclamped and a finished part is ejected. Injection molding offers the lowest piece prices available, but tooling prices are generally the highest. Thermoset injection molding is similar to thermoplastic injection molding except that uncured thermoset resins are mixed, injected, and held in the mold until cured. As with thermoplastic molding, the price per piece can be low, but the tooling prices are generally very high.

Purchasing the box, some assorted socket rails, and some additional clips for the socket rails, I took the box home with me to see how well it would stand up as a replacement. The box is quite simple in construction. It’s a plastic injection molded case made of a very thick plastic. The case consists of a flip open lid (with two latches that are padlock compatible) covering a deep top storage area, and three drawers that are very similar to the large rolling tool chests that many professionals and advanced amateur home mechanics have in their garages. When you flip the lid open, the lid will immediately release the latching mechanism for the three drawers. Unfortunately, the lid does not contain any hinges or tethering that prevent it from flopping open and hitting itself on the back of the tool box. This was my only gripe involving the tool box.
