Plastic is really a huge industry comprising of many players. Here, we’ll have a look at who they are and what services or products they provide.
When asked to describe the plastic industry, a lot of people tend to focus first on the “plastics product manufacturers “.Let’s start with your manufacturers and we’ll radiate out to see who else assist these manufacturers before something is finally produced and sent to the consumers.
There are 2 ways to describe what a producer does – either by process (the plastics making methods they use), or by a they are serving (packaging, automotive, etc.). The last product to be manufactured determines the sort of processes to be used. It’s not necessary that the manufacturer be built with all known processes. Most manufacturers are specialized in mere 1 or 2 methods. Bigger plants might have 3 or 4 but it’s rarely possible to own every process under one roof since the choice of process is influenced by the ultimate product and industry that the manufacturer is supplying to. Eg, a business that supplies to the electronic industry might have injection molding process to produce TV casing and other components. Blow molding processes that are accustomed to make bottles are of little use to them.
Plastics are used 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. Many 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.
There are many types of plastics materials. Within each kind of plastic materials, will vary grades – suited to different products and for several types of processes. Eg. PP (polypropylene) is really a common material and has many applications. However, PP materials which can be employed for making plastic bags will vary from those who are accustomed to make car bumpers – although they could originate 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 in making plastics. Here, they convert by-products from crude oil refineries to produce plastic materials. Different resin producers specialize in several types of materials. They supply large quantities to manufacturers (those who consume a hundred or so a lot of the exact same material monthly) and to Resin Traders.
Resin Traders purchase 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 sizable selection of different materials.
Colorants and Additives Suppliers – Many 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 change certain characteristics of a material. Eg. UV stabilizer is really a common additive that’s added to plastic materials to prevent discoloration of the merchandise from long experience of 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 a lot of materials at a time. Compounded materials are far 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 occasions where plastic goods are shaped manually by hand. These machines form the back bone of each manufacturing plant and the machine makers are categorized on the basis of the process they are 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 seed run efficiently. Examples of such machines are Hopper Dryers for drying materials, Mixers for mixing material, Robotics for extracting products from the machine, material handling system, conveyor systems, etc.
Mold Fabricators – Molds are mounted onto the processing machines which plastics part takes its form or shape. With respect to the process, corrugated plastic manufacturers some molds can be extremely complicated. Mold makers specialize in precision tools to cut blocks of steel into the required shapes. With assistance from advance CAD/CAM softwares (Computer Aided Design/Computer Aided Machining), they give the blueprint for the ultimate product.
Technical and Engineering Services – With respect to the industry that the maker is supplying to, some products require various standards adherence certification before their goods are sold. Eg, car bumpers are subjected to certain automotive standards to ensure the part is strong enough to withstand collision impact and these companies provide such tests.
Secondary Processes is really a very broad term. It generally describe the extra work that have to be done after the parts are produced. This include printing, painting, polishing, trimming, etc. Although most manufacturers are built with some form of common secondary processes, some specialized process like chrome plating tend to be carried out by the specialists.
