MWC's permanent magnetic field further breaks down minerals into smaller particles making them more bio-available to the plant cells. The bottom line results are nothing but miracle : maximum hydration of healthy water with greater uptake of minerals results in greater yields, larger and better end product, earlier maturation, longer shelf life, and healthier plants. It allows a reduction of amount of water needed, fertilizer and pesticides. Since the magnetic structuring breaks all minerals into smaller particles, salt in the soil is broken down by the structured water, causing it to sink deep into the soil, away from plant roots, and wash away. The desalinization happens quickly over a season, creating much healthier plants, greater yields, and better final product. Since the hexagonal water molecule cluster won't allow the bonding of minerals to it, magnetically structured water acts as Good Solvent which removes scaling from pipes and won't allow new scaling to take effect.
Ammonium polyphosphate is an inorganic salt of polyphosphoric acid and ammonia containing both chains and possibly branching. Its chemical formula is [NH4 PO3]n(OH)2 showing that each monomer consists of an orthophosphate radical of a phosphorus atom with three oxygens and one negative charge neutralized by an ammonium cation leaving two bonds free to polymerize. In the branched cases some monomers are missing the ammonium anion and instead link to three other monomers. The properties of ammonium polyphosphate depend on the number of monomers in each molecule and to a degree on how often it branches. Shorter chains (n1000),[1] but short polymer chains (e.g. pyro-, tripoly-, and tetrapoly-) are more soluble and show increasing solubility with increasing chain length. Ammonium polyphosphate can be prepared by reacting concentrated phosphoric acid with ammonia. However, iron and aluminum impurities, soluble in concentrated phosphoric acid, form gelatinous precipitates or "sludges" in ammonium polyphosphate at pH between 5 and 7.[3] Other metal impurities such as copper, chromium, magnesium, and zinc form granular precipitates.[4] However, depending on the degree of polymerization, ammonium polyphosphate can act as a chelating agent to keep certain metal ions dissolved in solution.

Mold Assembly When designing plastic injection moulded parts to be used in conjunction with other parts, the assembly must be considered. There are several assembly techniques, mechanical fastening, press fit, hot staking, snap fit, welding, solvent bonding and adhesive bonding. Weâ??ll cover each of these in more detail over the next two articles and how they fit into the design process. When designing for plastic injection moulding, the aim is to reduce the overall number of parts for any given product. There are several advantages to this aim, not only will it reduce costs but it will make assembly easier. When designing, designers should lookout for any opportunities to simply the assembly process through a more efficient design. Details of Injection Molding and Assembly Six Points Of Preparation For Mold Assembly Familiarity with assembly procedure A thorough understanding of assembly drawings Checking Parts Mould Acceptance Technology Developing Assembly Sites Preparing mold standard parts and related materials DESCRIPTION OF INJECTION MOLD ASSEMBLY How to Design for Assembly Searching for Symmetry It might be hard to wrap your mind around at first, but many assemblies traditionally constructed of two unique components can often be made from a pair of identical parts. Self-Mating Parts But why not get rid of the screws altogether? Our gear housing example is now symmetrical, but it still requires manual installation of threaded inserts, never mind keeping track of all those pesky screws and washers. Family Molds Another way to achieve hero status is the use of family molds, which are ideal when producing a series of parts with similar shapes and sizes. Hardware Harmony Everyoneâ??s heard the adage about reinventing the wheel. Designing and manufacturing your own nuts, screws, shafts, pins, keys, and dozens of other off-the-shelf components should be avoided at all costs. Better to redesign your product around standard hardware items, especially if production volumes are expected to rise at some point. Moving to Monoform The properties that make plastics such as polypropylene (PP) and styrene butadiene (SB) excellent candidates for living hinges.es of the chosen plastic are appropriate for the environment in which theyll be used. Easy Assembly If a product must be assembled, attempt to make the task easier by orienting the various screws and connectors in such a way that all are accessible from the same side, thus minimizing part flipping and rotating.

PLA is not plastic. It is derived from nature. Starch is extracted from plants such as corn and cassava and fermented by microorganisms to produce lactic acid. Lactic acid undergoes an advanced polymerization process to produce a 100% green and safe new polymer material called polylactic acid (PLA). Products made from this material are healthy and safe, non-toxic and odorless, and have no harm to the human body. In addition, if the product is discarded under composting conditions, it can be completely decomposed by microorganisms, eventually generating carbon dioxide and water, and returning to nature. The environment does not cause any pollution, so PLA is recognized as a â??green materialâ?? for low-carbon environmental protection and sustainable development in the 21st century.

Core and cavity are used in the injection molding process, where the concave part of the mold is the cavity and the convex part is the core. The core and cavity in injection molding are used in pairs, with the cavity also referred to as the female mold and the core as the male mold. DESCRIPTION OF CORE AND CAVITY What Does Core Mean In Casting? A core is a preformed, bonded, sand insert placed into the mold to shape the interior of a casting or a part of the casting that cannot be shaped by the pattern. Cores are frequently used to create hollow sections or cavities in a casting. Function Of Core And Cavity The core & cavity are the shaped sections in either half of the mould tool which give the plastic product its final shape. The hot molten material is injected into the core & cavity and then sets hard into shape. The core and cavity design of this type of mold spare parts is essential in the correct formation of the product. DETAILS OF CORE AND CAVITY What Are The Types Of Core? Generally, cores are of two types: Green Sand Core: ADVERTISEMENTS: A core formed by the pattern itself, in the same sand used for the mould is known as green sand core. The pattern is so designed that it provides the core of green sand. The hallow part in the pattern produces the green sand core. Dry Sand Core: A core is prepared separately in core boxes and dried, is known as dry sand core. The dry sand cores are also known as process cores.

EverFlon ®PTFE Dispersion Fine Powder F500 is a soft white polymer made from a water-based dispersion of PTFE. These fine powders have the lowest coefficient of friction, highest heat resistance, chemical resistance, electrical properties and non-stick properties of all fluoropolymers. It has the unique ability to shear a lubricating paste by extruding it into a bonded fiber matrix with useful structural integrity. EverFlon ®PTFE F500 is designed for machining at medium and high pressure rates from 100:1 to 600:1. It is particularly suitable for the production of high quality tubes, spiral tubes and wire coatings. This grade is also well suited for post-processing techniques such as flanging, welding, blow molding and turning. Processing suggestion EverFlon ®PTFE F500 is extruded using liquid processing AIDS such as naphtha. During the paste extrusion process, the powder is mixed with a lubricating agent and then compressed under light pressure (1.5-2.0 MPa[220-290 psi]) into a cylindrical pre-formed bad material. The preformed blank is placed into the barrel of the paste extruder, where the composition is passed through a finishing die under high pressure to produce foaming, tubing or wire coating. After extrusion, the product has a low density but coherent fiber structure. PTFE F500 is usually processed under heat in a step-by-step process into solid resin products, such as tubes. Heating is carried out in two steps, either simultaneously with extrusion or separately. Usually the lubricant must be removed first by heating in a temperature range of 100-300°C(212-572°F). A sintering step is then performed to melt the resin above its melting point of approximately 342°(648°F) and produce a non-porous solid PTFE resin.
