MASTER injection mold maker box has a unique performance advantages

In recent years , with frequent fire accidents , people are wary of awareness of fire Continuously strengthened. According to According to the survey found that most of the fires because of reason and meter boxes , and therefore , how to prevent the meter box on fire the fire department is the focus of publicity .?Most people use the meter box with wooden and iron are two main shell material . However , whether it is business MASTER pe pipe fitting mold as usual iron meter box of wood , fire two warning functions are not perfect . To change the status of the meter box , a new meter box been developed , and is a lot of promotion of the use of , which is fire retardant FRP meter box .The new fire-retardant FRP meter box uses SMS, DMC unsaturated polyester resin fiberglass reinforced plastic produced by molding . With reliable insulation properties , high strength, flame resistance , corrosion resistance , aging resistance, shape fresh , bright and clean appearance mobile site production, service life more than 40 years in the indoor and outdoor for more than 30 years , is no other metal plastic meter box match. The productsMASTER injection molding supplies  are widely used in residential construction , public electricity transformation can be any combination of multi-family , single-family or inter- household can install , easy construction, traces lurking , this product uses harsh rain design, suitable for outdoor installation , ensure An electric meter run .

Meter box to use features editor

Completely solve the cabinet due to poor grounding and personal injury or death caused by foreign objects overlap; Integrated use of low cost, one-time investment can be used for more than 20 years (eliminating the metal cabinet replacement work and reaction injection mouldingcumulative costs); The unique design of the cabinet can effectively fight against external shocks; High cabinet material recovery costs, theft phenomenon prevents the body; Splicing can reduce the cost of maintenance box (you can replace only the damaged part); High temperature combustion gas does not injection moulding companiesproduce suffocation. Overall, the manufacture of fiber-reinforced polyester material with a low voltage cable branch box insulation, corrosion resistance, long life, easy installation, and many other advantages.

Meter box electrical properties

Used in the manufacture of electrical products, fiber reinforced polyester material has the following plastic rattan garden furniture mold electrical properties: Insulation Resistance (soaking 24h): 1.0x10 MΩ Arc resistance: 180s Proof tracking index: ≥ 600v Insulation protection and anti-creepage indicators in line with DIN / VDE standards. This material not only has excellent electrical insulating properties, and are plastic injection toy mouldable to maintain a good dielectric properties from electromagnetic effects at high frequencies, does not reflect electromagnetic waves. These properties can be compared to the far non-metallic materials.

Why thin wall injection molding

Why thin wall injection molding?Cost of plastic usually account for a large proportion of the cost of the wheel covers molding finished product, such as 50-80%. Help reduce the ratio of the number of thin-walled. By theIn consumer electronics devicesmake plastic molds such as mobile phones, MP3 players, digital cameras, handheld computers and portable technology miniaturization, the design of the plastic parts of it gettingthinner.

Mold temperature

Conventional injection molding melt filling time is very short , often simplified flow analysis isothermal filling , however , this simplification does not apply in the micro- injection molding . Micro- structure of small and micro injection molding products runner size , surface area to volume ratio, large cooling area per unit volume of the melt . When injected into the micro- structure of the melt , the melt volume is small, contained fewer calories , then melt temperature will drastically reduce the temperature of the cavity wall , and the rapid formation of condensate layer . Polypropylene (PP) , for example, according to the formula ( 1 ) estimated from the thickness of the condensate layer micro- structure and micro- structure size is quite possible , and this will inevitably affect the filling micro- structure.Custom plastic mold Shen micro injection (MM) and micro- injection compression (M ICM) forming a micro structure of poly (methyl methacrylate) (PMMA) light guide . The mold temperature was found to have a significant impact repeatability of the microstructure , with the increase of temperature of the mold , the article microstructure repetitive greater improvement ; micro- injection compression , the mold temperature factor is also significantly affected , as the mold temperature increases, the repeatability of the microstructure article greatly improved , but there is no improvement in the former a large amplitude .Xie and other devices using visual observation of PP melt weld line formation in micro- flow channel , and according to the characteristics of the mold design Custom injection moulding heating and cooling devices. Found that when the mold temperature is below the polymer glass transition temperature will increase if the injection pressure, the micro- channel can not be fully populated ; when the mold temperature is higher than the glass transition temperature of the polymer , at a lower injection pressure the filling can be obtained preferably microfluidic channel . Other scholars have studied experimentally derived products mold temperature on the microstructure has a significant impact on the repeatability .

Casting mold procurement

Choose a good reputation, high technology, experienced professional die casting mold manufacturing plant. Casting mold is a special precision machinery, those professional die casting factory, Crate mold they have die-casting molds for the production of precision machine tools, molds to ensure dimensional accuracy; They have experienced senior mold technicians and experienced technicians are good practical casting molds with assurance; they have a close relationship with material suppliers and heat treatment plant, Plastic pallet mould they have a sound service system  Good die casting mold design and manufacturing are long-life, low failure, high efficiency foundation. Low-cost low-quality die casting, die casting production will be exhibited low productivity, high fault, so you waste a lot of expensive die-cast working hours, spent more money.
