is an extremely versatile method of producing plastic parts and has multiple advantages over other methods of plastic molding.Not only is the process simpler and more reliable than others methods, but it is also extremely efficient.
Let's take a look at thetop six advantagesof this process:
Injection molding is the most common plastic molding process and is used to create a wide variety of complex parts of different size and shape.Whether it's an overcap for a water bottle or a vinyl window part being manufactured, injection molding is efficient and economical, especially if high volumes of parts are being produced.
Although plastic injection molding has advanced significantly over the years, it's still based on the same standard principles it was years ago!today's technological developments have only further enhanced its versatility and reliability.
During, plastic particles are melted down and injected into molds, which are chilled via water or a coolant that allows the plastic to harden.Once it has hardened, it is ejected from the mold and ready for use.
When engineering the wall thickness of a plastic part, a careful balance of weight, geometry, and budgetary considerations must be maintained.For example, while thick plastic walls offer more strength, they also have a greater tendency to warp during the cooling stage of the manufacturing process.
The success and precision of a part depends on the quality of its mold, but building a reliable, long-lasting tool can take a considerable amount of time — and requires a great deal of accuracy.Also, molds are often one the largest capital investments in a project, so it's critical that tooling is built right the first time around.This is particularly important in high-volume injection molding projects, where molds can be extremely complex.
To ensure consumer health and safety, thefood and beverage industrymust adhere to stringent specifications— requiring nontoxic parts, BPA-free components, and FDA certification.For plastic injection molding in these food service applications, various food grade materials must be used.
How often do you source aplastic injection molder? If you are like most companies and purchasing managers, probably not very often.Typically, once you have selected an injection molder to work with, you are likely to stay with them for a long time as long as they keep producing quality plastic parts.
Although metal-to-plastic conversion was introduced in the 1950s, with the invention of engineering-grade resins, many manufacturers today are unfamiliar with the advantages of this versatile technique.
As we discussed inthe first part of this blog series, turnkey manufacturers provide a one-stop shop for customers in search of quality custom parts!the process begins with a new design and ends with a final product requiring only "the turn of a key" to get started.Design, tooling, production, packing, and shipping are all managed in one place, by a single team of experts.Material selection, professional sourcing, and even invoicing are streamlined for low pricing, high quality, and optimal efficiency.
