Plastic is really a huge industry comprising of many players. Here, we’ll have a look at who they’re 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 use these manufacturers before a product is finally produced and brought to the consumers.
You will find 2 ways to describe what a supplier 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 produced determines the kind of processes to be used. It’s not necessary a manufacturer be equipped with all known processes. Most manufacturers are specialized in only 1 or 2 methods. Bigger plants may have 3 or 4 but it is rarely possible to own every process under one roof since the choice of process is determined by the final product and industry a manufacturer is supplying to. Eg, a company that supplies to the electronic industry may have injection molding process to make 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. While most 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 kind of plastic materials, are different grades – suited for different products and for different types of processes. Eg. PP (polypropylene) is really a common material and has many applications. However, PP materials that are employed for making plastic bags are different from those that are accustomed 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 to make plastics. Here, they convert by-products from crude oil refineries to make plastic materials. Different resin producers specialize in different types of materials. They supply large quantities to manufacturers (those who consume a few hundred 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 large selection of different materials.
Colorants and Additives Suppliers – While most materials are transparent or translucent in its natural state, colorants are added to provide it different shades of colors. Additives are chemical agents added to improve certain characteristics of a material. Eg. UV stabilizer is really a common additive that’s included with plastic materials to avoid discoloration of the product 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 can handle mixing several a lot 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 produces the product. Gone are the times where plastic items are shaped manually by hand. These machines form the trunk bone of every manufacturing plant and the device makers are categorized on the basis of 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 plant 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 which plastics part takes its form or shape. With regards to the process, some molds can be quite complicated. Mold makers specialize in precision tools to cut blocks of steel into the required shapes. With the help of advance CAD/CAM softwares (Computer Aided Design/Computer Aided Machining), they offer the blueprint for the final product.
Technical and Engineering Services – With regards to the industry that the maker 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 really a very broad term. It generally describe the excess work that must be done after the parts are produced. This include printing, painting, polishing, trimming, etc. Although most manufacturers are equipped with some type of common secondary processes, some specialized process like chrome plating tend to be carried out by the specialists.
