Plastic Injection Molding Myth: Plastic molding is unsuitable for prototyping. For many of the above reasons, plastic injection molding has a reputation of not being an appropriate process for prototyping parts.

It may be called “not cost-effective” or “too time-consuming.” All too often, another process is used to create a prototype, which doesn’t provide the same similarity to the finished product as injection molding might.

In reality, injection molding, when the right processes are used, can easily provide cost-effective prototypes in as little as a few days; letting the entrepreneur or other product developer get a sense of how the actual finished product will look, feel and function.

Why plastic is so expensive?

The upfront costs of making a cheap plastic product often comes as a bit of a shock to new product developers. The basic reason for this is that steel is expensive, especially the high quality steel used in plastic injection molding machines. The metal mold tool used to make inexpensive cell phone cases can cost more (and contain more steel) than a car.

UPFRONT COSTS = This pays for the fabrication of a mold tool. The tool material (plastic, aluminum, or high grade steel) is the single largest cost of developing most plastic parts. It’s often said, “The first part costs you $100k. The second costs you $1.”

TRUE COST PER UNIT = All the costs of manufacturing, including the upfront tooling costs, divided by the volume. Characterized by the equation; Upfront Costs + (Cost per unit X Volume) / Volume. You may more commonly see just the Cost per Unit, basically the cost of plastic, specified when describing plastic production costs. This value includes that and the upfront cost of the tooling combined.

VOLUME = Number of parts or units to be fabricated.

Most companies make sourcing decisions based solely on price, oftentimes resulting in a 20 to 30 percent miscalculation of actual offshoring costs. The Total Cost of Ownership (TCO) Estimator is a free online tool that helps companies account for all relevant factors — overhead, balance sheet, risks, corporate strategy and other external and internal business considerations — to determine the true total cost of ownership.

Benefits of the Total Cost of Ownership Estimator:

Customized: Calculations are based on your unique data.
Flexible: Users may skip values that are not essential
Enables direct comparisons by providing a total cost for each source
Complete: Incorporates 30 cost and risk factors
Strategic: Provides the current TCO value, as well as a 5-year forecast based on the user’s forecast of wage and currency changes
User-friendly: Automatic calculation of freight rates for 17 countries and explanations and references for Input factors.
Transparent: Cost calculation formulas are shown on the Results page
Credible: Recognized by the U.S. Commerce Dept.
Affordable: Free to use

Plastic Injection Myth: "Injection molding is only suitable for long production runs." In fact, injection molding can be a cost-effective solution for producing a part in nearly any quantity, from prototypes of a few pieces up to large-scale, six- or seven-figure runs. Even for functional prototypes produced from just one cycle, injection molding can provide a solution.

Plastic Injection Molding Myth: Manufacturing a mold is exceedingly expensive. This does not have to be the case. While tool steel molds require extensive time and provide unparalleled strength for full production runs — and thus cost a commensurate amount of money to produce — other materials can be used to create molds for shorter run applications. Molds can be 3D printed or even CNC machined from other materials, all at a lower cost than the traditional tool steel mold.

"HOW do they make that?!" It is difficult to avoid that question when I pick up something like a one-shot molded chain. They do incredibly tight work at #Lego. Unable to find out how they mold chain, I worked it out and made this video. I'm sure they weren't the first to mold chain, but they may be the best. #DaleEmery
