Plastic is just a huge industry comprising of many players. Here, we’ll take a peek at who they’re and what services or products they provide.
When asked to spell it out the plastic industry, a lot of people tend to target first on the “plastics product manufacturers “.Let’s start with your manufacturers and we’ll radiate out to see who else use these manufacturers before an item is finally produced and brought to the consumers.
You can find 2 ways to spell it out what a producer does – either by process (the plastics making methods they use), or by the industry they are serving (packaging, automotive, etc.). The ultimate product to be produced determines the type of processes to be used. It is not necessary a manufacturer be designed with all known processes. Most manufacturers are specialized in only a couple of methods. Bigger plants may have 3 or 4 but it is rarely possible to possess every process under one roof since the choice of process is influenced by the ultimate product and industry a manufacturer is supplying to. Eg, a company that supplies to the electronic industry may have injection molding process to create TV casing and other components. Blow molding processes that are used to make bottles are of little use to them.
Plastics are employed extensively by different industries. These industries includes: medical and pharmaceutical; packaging; electronic and electrical; automotive; toys; building and construction; home products; agriculture; and many more. Some manufacturers sell their plastic parts and products to others industries, some trade among themselves. Eg. Plastic bags manufacturers who specialize on producing bags will sell them to other plastics manufacturers for packaging purposes.
You can find various types of plastics materials. Within each form of plastic materials, will vary grades – fitted to different products and for various kinds of processes. Eg. PP (polypropylene) is just a common material and has many applications. However, PP materials that are useful for making plastic bags will vary from those who are used to make car bumpers – although they might result from the exact same material suppliers that are also known as Resin Producers.
Resin Producers are petrol-chemical plants that produce plastic resins – the raw material for making plastics. Here, they convert by-products from crude oil refineries to create plastic materials. Different resin producers specialize in various kinds of materials. They supply large quantities to manufacturers (those who consume a hundred or so tons of the exact same material monthly) and to Resin Traders.
Resin Traders buy the raw material from resin producers and sell to manufacturers in smaller quantities. A trader will often represent several resin producers thus providing manufacturers with a big selection of different materials.
Colorants and Additives Suppliers – Some materials are transparent or translucent in its natural state, colorants are added to give it different shades of colors. Additives are chemical agents added to alter certain characteristics of a material. Eg. UV stabilizer is just a common additive that’s added to plastic materials to prevent discoloration of the merchandise from long contact with sunlight.
Compounders are firms that specializes in “mixing” materials, additives and colorants in large quantities. They operate large scale mixing machines that are capable of mixing several tons of materials at a time. Compounded materials are more consistent than those mixed by manufacturers in smaller quantities using small mixers.
Machine Suppliers provide manufacturers with machines that produces the product. Gone are the times where plastic items are shaped manually by hand. These machines form the back bone of every manufacturing plant and the device makers are categorized based on the process they’re specialize in. Such processes include Injection Molding, Blow Molding, Stretch Blow Molding, Blow Film, Profile Extrusion, Sheet Extrusion, Rotation Molding, Compression Molding, etc.
Auxiliary Equipments Suppliers supplies various supporting machines and equipments to help a place run efficiently corrugated plastic manufacturers. Types of such machines are Hopper Dryers for drying materials, Mixers for mixing material, Robotics for extracting products from the device, material handling system, conveyor systems, etc.
Mold Fabricators – Molds are mounted onto the processing machines on which plastics part takes its form or shape. With respect to the process, some molds can be very complicated. Mold makers specialize in precision tools to cut blocks of steel into the specified shapes. With the aid of advance CAD/CAM softwares (Computer Aided Design/Computer Aided Machining), they provide the blueprint for the ultimate product.
Technical and Engineering Services – With respect to the industry that the manufacturer is supplying to, some products require various standards adherence certification before their items are sold. Eg, car bumpers are put through certain automotive standards to ensure that the part is strong enough to withstand collision impact and these companies provide such tests.
Secondary Processes is just a very broad term. It generally describe the additional work that must be done following the parts are produced. This include printing, painting, polishing, trimming, etc. Although most manufacturers are designed with some form of common secondary processes, some specialized process like chrome plating tend to be carried out by the specialists.
