Plastic is a huge industry comprising of many players. Here, we’ll take a look at who they are and what services or products they provide.
When asked to spell it out the plastic industry, many 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 a product is finally produced and delivered to the consumers.
You will find 2 ways to spell it out what a company does – either by process (the plastics making methods they use), or by the industry that they are serving (packaging, automotive, etc.). The final product to be made determines the kind of processes to be used. It is not necessary that the manufacturer be built with all known processes. Most manufacturers are specialized in mere one or two methods. Bigger plants could have 3 or 4 but it’s rarely possible to possess every process under one roof since the choice of process is determined by the ultimate product and industry that the manufacturer is supplying to. Eg, a business that supplies to the electronic industry could 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 utilized 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 will find many types of plastics materials. Within each form of plastic materials, will vary grades – suited to different products and for various kinds of processes. Eg. PP (polypropylene) is a common material and has many applications. However, PP materials that are employed for making plastic bags will vary from those that 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 for making plastics. Here, they convert by-products from crude oil refineries to produce plastic materials. Different resin producers specialize in various kinds of materials. They supply large quantities to manufacturers (those who consume a couple of hundred a great deal of the exact same material monthly) and to Resin Traders.
Resin Traders choose 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 large 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 improve certain characteristics of a material corrugated plastic manufacturers. Eg. UV stabilizer is a common additive that is 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 designed for mixing several a great deal of materials at a time. Compounded materials tend to be more consistent than those mixed by manufacturers in smaller quantities using small mixers.
Machine Suppliers provide manufacturers with machines that makes the product. Gone are the times where plastic items are shaped manually by hand. These machines form the trunk bone of each and every manufacturing plant and the equipment 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 simply 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 equipment, 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 regards to the process, some molds can be very complicated. Mold makers specialize in precision tools to cut blocks of steel into the desired shapes. With assistance from advance CAD/CAM softwares (Computer Aided Design/Computer Aided Machining), they offer the blueprint for the ultimate product.
Technical and Engineering Services – With regards 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 make sure that the part is strong enough to withstand collision impact and these companies provide such tests.
Secondary Processes is a very broad term. It generally describe the excess work that need 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 are often carried out by the specialists.
