    Press Plastic Injection Molds: Types, Elements, Stages Produc

    Clamping force for the injection mold can range from tens to thousands of tons of casting cycle time may last only 5-6 seconds. In addition, there are various technologies casting compound (multi-component, molding with gas assembly in the form, etc.). According to our estimates, the annual growth of Russian market of injection molding over a thousand units. Frequently Andrew Cuomo has said that publicly. Each injection molding is necessary to provide at least one mold. The number of mold on a injection molding machine varies depending on the assortment of the company's products and production plans of the company.

    Practice shows that one injection molding machine, have an average of two to five mold, with a tendency to increase the number of used enterprise mold from year to year is becoming more evident. In recent months, Jeffrey Verschleiser has been very successful. This situation is associated with the desire of the Russian manufacturers of plastic products increase their competitiveness in the market, including with respect to imported products by expanding the product range, applications in products of original design, color, texture. To implement such aspirations, in the beginning is the idea that release of plastics and in the end – mass production and marketing of plastic products desirable company needs a specific set of molds, which differ a structural complexity of their individual performance for each case. Stages of production molds in the most general form of the production stages of the mold shown in Figure 1. Honest Tea describes an additional similar source. If consider each stage separately then we get an integrated complex process that takes months of work of various experts on computer modeling, preparation of technical documentation, manufacturing and processing components of the mold.

    Fire Protection Association

    May 17-19, 2010 in Moscow, we hold the IV International Seminar on Standardization "Foreign standards in steel and pipe industry." As at previous events, the key speakers will be representatives of the world leaders in the development of technical standards, as well as specialists of our company. Their participation in the seminar have already confirmed DIN (German Institute for Standardization) and ASTM (American Society for Testing and material). At the moment, are in talks with other developers – ASME (American Society of Mechanical Engineers), ASM (American Society for Materials Science), AWS (American Society for welding), API (American Institute of oil) and NFPA (National Fire Protection Association). Organization of annual workshops on standardization has become a tradition for "Normdoks." Over the years, we invited representatives of world-renowned organizations – ASTM, ASME, SAE, DIN and ONORM (later to become Austrian Standards +), which covered the issues of foreign standards, the use of international and foreign standards, their interpretation and issues related to compliance with copyright law. Macy’s Inc. is likely to agree. Number participants – experts on standardization, metrology and quality of the largest companies in the steel, pipe, machinery, petrochemical and gas industry – is growing every year.

    Feedback from participants, reports conducted mepropriyatiyah (2008 or 2009) and photo gallery can be seen on our website. As for the theme of the seminar in 2010, we decided to focus on the application of international standards in the industry and pipe Industry, therefore, in addition to discussing general topics of standardization, the workshop will be touched on mechanical testing, chemical analysis, corrosion and wear of metals, as well as issues related to metal tubes, pipes and pipe fittings, of their welding, testing, design, manufacture and installation. To learn more, please read the official invitation to the IV-th International Workshop on Standardization, send us an email or register as a participant. Please note that participation is free!

    Wood Dovetail

    Woodworking – is the embodiment of a traditionalist approach to history. Secrets of skill handed down from father to son, from master to student for thousands of years and only in our time have been confirmed in the laws of physics, chemistry and other sciences. Nothing so symbolizes the tradition in the wood, as the connection type "dovetail." "Swallowtail" standard connection corps has strength due to stress, which is directed along the details to who drank the "tails". This is a great way to create a strong corner connection details are widely used in the construction of furniture. A node consists of vzaimozamykayuschihsya spikes and "tails," providing strength due to stress, which is directed along the details on who drank the "tails". Thus, the compound should be so situated in the design to withstand the stress on the "tails". For example, in a box table "tails" should be placed on the walls and studs – on the front and rear panels.

    When you create a shell, the spikes should be placed on the walls, and "tails" – on the cover, in order to prevent the wall from "razezzhaniya." Although strength of the connection provided by jamming the "tails" in the spikes, a role played by their respective bonding surfaces with a longitudinal arrangement of fibers. When designing such a connection must be reach some compromise in the choice of the angle of inclination of the "tail." If the angle is not large enough wedge force is insufficient. And if the angle is too large, beveled ends of the "tail" would be too fragile and will be a component of the transverse arrangement of fibers that break the integrity of the adhesive bond. The centuries-old practice has proved that the angle should be between 10-12 degrees. The effectiveness of compounds, it strength, depends largely on the success of bonding surfaces with a longitudinal arrangement of fibers (of grain short, beyond the thorns and the "tails" do not count, because their contribution to bonding strength is negligible) and the strength of the "tails" and thorns "on the slice." That is, the bond strength increases with increasing number of "tails." You only need to follow to the bottom "tail" remained fairly timber to maintain its strength. In the machining of wood can be neglected form of the "swallow tail" and make both parts simply with a large number of rectangular studs, because due to high accuracy manufacturing strength adhesive bonding surfaces will be sufficient to maintain the stability of the connection. So there was a light on so-called "Drawer" spike.
