This guide provides general information on the most common manufacturing processes for producing plastic parts, as well as recommendations to help you choose the best option for your application.How to choose the right plastics manufacturing processConsider the following factors when choosing a manufacturing process for your product:
Volume/cost: What is the total or annual volume of parts you plan to manufacture? Some manufacturing processes have high upfront costs for tooling and setup, but produce parts at an economical cost per part. On the other hand, low-volume manufacturing processes have low up-front costs, but due to slower cycle times, less automation and manual labor, the cost per part remains constant or decreases only slightly as volume increases.
Lead time: How fast do you need parts or finished products to be produced? Some processes create the first parts in less than 24 hours, while tooling and fixturing for certain high-volume production processes require months.
PVC resin
In the polyester factory, tools and materials are used to achieve the desired end. Because at the beginning the polyester is liquid and for it to become rigid the joint action of accelerator and catalyst is required. In addition, there is the resin that gives it consistency against humidity, high temperatures, chemicals, etc.
Nowadays, pre-accelerated resins are applied in the polyester manufacturing process to achieve the rigidity of the part, but it will always be the catalyst that will finish the process.
Liquid plastic resin
We could list the number of plastic objects we have in our daily lives and fill pages and pages with our lists. But little do we stop to think about what type of plastic resin these objects have that are with us, most of them for life.
To begin with, we will mention that polymerization is the process by which all these resins are produced How is this magic generated? Through the monomers or chemical compounds of low molecular weight are grouped together forming a new compound: the polymer, the basis for the production of each of these resins.
When heated, the material behaves in a very peculiar way, as it becomes liquid when heated to around 105°. When it gradually returns to below its normal melting temperature the material solidifies, the polyethylene will not break or even bend.
Low density polyethylene (4) is a polymer that is characterized by its resistance to impact, has very good thermal and chemical resistance, and is more flexible than high density polyethylene.

By using material mixers, inventories are reduced to only the raw materials needed for the process, there are no prior compounding steps, and the regrind can be sent directly to the process without interrupting the flow.
Mixing is an efficient, complete and automated way to combine materials and ingredients in predetermined proportions, which will be added to the melt for the production of plastic parts or products. Processors can blend basic plastic resins with additives and colorants at their plant, according to their process and final product. This is less expensive than buying the premixed material from a supplier.
Dosing is the introduction of a specific material ingredient, such as color concentrate, to a separate stream of material in the process. Blending, on the other hand, controls all the ingredients in the throat of the machine, not just the dosed additive. Mixers are composed of several dosing units that work together to create the precise introduction of all materials into the process.
