import vs. Domestic Plastics Materials

import vs. Domestic Plastics MaterialsWhen it comes to cars or perhaps beer, we generally associate imports with higher performance or quality craftsmanship (depending on your taste of course). For the most part, we can all find something good about our favorite import beer or perhaps a european sports or luxury car that sets them apart in our mind. In plastics, there are many companies that import resin systems or stock shapes materials from very reputable and quality companies in Europe and Asia. There are times however that sourcing these items may have some risks, depending on what material is being sourced and from what manufacturer.If you have been reading this blog, you may already know that Plastics International sources and sells engineering plastic stock shapes all over the world. We have seen extremely good products that work well in demanding applications and we have seen some not so very good products fail and cause problems for job shops and their end users. Unfortunately, many times the motivation to use an import material is primarily motivated by a low price. But a low price can have some high priced consequences.Take for example Acetals. There is already a great deal of confusion in our industry about homopolymers acetal (Delrin) vs copolymer Acetal (i.e. Tecaform, Acetron GP, Pomalux). These two products are not the same and they each have their pros and cons. When copolymer Acetal is the right material for the job, there are many quality products that can provide a good, stable stock shape to machine from. Lately, we’ve been seeing a flood of generic imports of copolymer Acetal in the market. The primary reason these products have made their way into the market is not because of any issues with the established brands. The import products are being introduced because they are offering extremely low prices in order to gain market share. So these products will tell you about how they offer “competitive” pricing but they often leave out what they don’t offer. These suppliers do not offer things like in-house tech support or testing labs, consistent resin supply and quick turn around should there be material problems. In some cases the resins they use may not always come from the same supplier nor might they carry all of the same specifications or certifications.For many, this isn’t a problem or anything to worry about until something fails. The industry standard for stock shape manufacturers is to only credit for material, not labor. That means if a machined part fails, only replacement or credit for material is offered. Keep this in mind when a low priced import seems to good to be true. Plastics International offers a quality driven supply chain and accurate part numbers to ensure you know what material you are getting and that it will be the same high quality product on every order. Always ask for material certifications and don’t settle for “no-name” products from “no-name” manufacturers.

What does the mean Extrusion?

What does the mean Extrusion?the word extrusion is taken from the Latin word extrudere meaning (ex) out and (trudere) to push. In the extrusion process, a pellet or dry powder plastic is heated and forced through a die. The majority of extrusion is done by screws although ram extrusion is still used for UHMW powder specifically. The screws will melt and mix the material and force it out of the opening in the die. An extruder can either be single barrel or twin screw/double barrel equipment. The material being extruded determines what which extrusion technology is required. Double barrel extruders are primarily use for compounding in line of basic plastics with different plasticizers, fillers, colorants and other ingredients. Extrusion lends itself to make tube, rod, profiles, film or sheet plastic products in a variety of widths and thicknesses.Extrusion is one of the primary ways machine stock shape plastics are made. Extrusion has several advantages:-The high output (compared to other processes) offers lower material costs.-Depending on the volume, there can be a greater variety in width and length options to maximize yields.-Relatively low tooling costs.Extrusion can have some disadvantages:-Thickness limits for some materials.-From a machining standpoint, the material may have a higher level of stress in the sheet making secondary or post manufacturing annealing necessary to help relieve stress so the stock shape is more machinable.– Close tolerance shapes are difficult to achieve.-Limited to shapes of uniform cross sections (along the length).Extrusion is one of the most common ways to produce plastic stock shapes. When done by a reputable extruder, using the highest quality materials the machining of these stock shapes can be a successful part of any job shops business
