What does Triangle Tool excel at?

Simply put, we make you successful. Whether you’re a Fortune 500 company or a niche molder, molds that produce day after day are critical for increasing your business’s bottom line. We drive solutions that are the right fit for you and your business through open communication and our many decades of engineering experience. Setup a visit to see for yourself!

What does Triangle Tool need to know about your company?

Knowing your strengths and your weaknesses are the foundation that we build your tooling solutions around. It makes little sense to put a highly engineered tool into your shop if the workforce isn’t equipped to run and maintain the mold. But what if your toolbuilder could train your staff in the use of the mold at our facility and then also assist with startup? At Triangle Tool, we allow our customers to leverage our expertise – from engineering through processing.

Why won’t Triangle Tool's price be the lowest?

If your single biggest factor with a tooling supplier is price, Triangle Tool is NOT the Plastic Injection Moldbuilder for you. Whether you quote 3 shops or 20, the low shop is going to build you the cheapest mold possible. If it meets your expectations – great! If it doesn’t, at least you saved money upfront… When we supply you a quote, it’s based on your specifications and our knowledge of tooling and molding dynamics. The true value of a mold is not based on the price you give to your accountant but how well it performs in your molding press.
