A plastic product can be very durable and withstand a wide variety of stresses. Thermoplastics are used for everything, even where you'd least expect it!
This is a leap forward from the humble plastic container in your kitchen. If the indication isn't obvious, there are many types of plastic.<\/p>\r\n\r\n\r\n\r\n
Naturally, this means there are many criteria to consider when choosing the resin for your plastic product. Resin refers to the types of plastic, which vary enormously thanks to numerous technological advancements. Plastic Material<\/a>.<\/p>\r\n\r\n\r\n\r\n Your products might not need to go to the planet Mars, but the wrong plastic can ensure they don't go anywhere at all!<\/p>\r\n<\/blockquote>\r\n\r\n\r\n\r\n So, how do you choose the right resin? Here's a process to follow:<\/p>\r\n\r\n\r\n\r\n Here are some of the questions you should start with, as they will help you identify the characteristics you will want in your choice of plastic.<\/p>\r\n\r\n\r\n\r\n Pay attention to every design requirement, even texture and appearance. These will guide your choice of resin.<\/p>\r\n\r\n\r\n\r\n There are broadly two types of plastics: thermosetting plastics and thermoplastics. Their names indicate their notable difference:<\/p>\r\n\r\n\r\n\r\n Thermosetting plastics are cured by heat. They are essentially baked, making them incredibly durable but also almost impossible to recycle. If your product needs to withstand significant temperatures, this family of resins should be your choice.<\/p>\r\n\r\n\r\n\r\n These materials can be processed by injection, compression, pultrusion, etc. Rubbers and silicones are also related to these substances. Hysbter does not specialise in these types of materials.<\/p>\r\n\r\n\r\n\r\n But Most plastic applications use thermoplastics<\/strong>. These types of resins are melted to take the shape of the finished product, and then retain this shape once cooled. injection molding<\/strong> plastic and 3D FDM printing<\/strong> This family of resins is used. It should be mentioned that thermoplastics can withstand heat if designed to do so. But generally, these resins will eventually melt at sufficiently high temperatures.<\/p>\r\n\r\n\r\n\r\n Once again, there are several choices:<\/p>\r\n\r\n\r\n\r\n Base resins are intended for high production volumes and low costs. Plastic bags, packaging, toys, appliance buttons and the like are typical examples.<\/p>\r\n<\/div>\r\n Technical resins have superior mechanical and thermal properties and are often used to create industrial parts.<\/p>\r\n<\/div>\r\n High-performance resins are really strong and lightweight, which is why they are the most common in the aerospace industry. They are also significantly more expensive.<\/p>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n\r\n Do you remember the trip to Mars? Well, you won't get there if you use the first two types of materials.<\/p>\r\n\r\n\r\n\r\n Should we favour the cheapest material? The most expensive? \u2026.. we\u2019ll help you understand!!<\/p>\r\n\r\n\r\n\r\n First point:<\/strong> You\u2019ll need three times less material (it\u2019s not exactly a linear relationship, but never mind \u2013 this is just to illustrate the calculation!) containing 20% glass fibres than standard material\u2026 so if you buy the material for less than three times the price of the standard one, you\u2019ve made a saving! Easy, isn\u2019t it?<\/p>\r\n\r\n\r\n\r\n Second point:<\/strong> The machine's cycle time is proportional to the product's thickness (squared!)... so not only do we produce fewer parts per hour (hence a higher unit cost), but we will also spend more energy.<\/p>\r\n\r\n\r\n\r\n Third point:<\/strong> The material doesn't have the same density either! So if you fill a mould (in litres), and the density isn't the same... you get a different weight! (since we buy by the kilo... that changes things further).<\/p>\r\n\r\n\r\n\r\n Nevertheless, there are applications where a standard resin will be more advantageous than a technical resin... but we'll explain that later!<\/p>\r\n Hybster a d\u00e9velopp\u00e9 un comparateur de mati\u00e8res plastiques innovant, vous permettant de choisir la meilleure mati\u00e8re pour votre projet.<\/a><\/p>","protected":false},"author":15,"featured_media":1526,"template":"","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_uf_show_specific_survey":0,"_uf_disable_surveys":false},"famille-de-documentation":[964,967],"class_list":["post-4923","documentation","type-documentation","status-publish","has-post-thumbnail","hentry","famille-de-documentation-conception-produit","famille-de-documentation-matieres-plastiques"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\r\n
