Monroemold Testimonial


  • “Monroe Mold is fantastic to work with, they always do better than their lead-times, they are responsive to our crazy needs and they are just downright pleasant to work with. I like that you give us a written schedule each week, this saves a phone call.”

  • “I’m always amazed how fast Monroe Mold can turn stuff around.”

  • “I just wanted to take the time again to thank you guys and your crew for the great job you did in getting this difficult mold fabricated. We asked a lot out of you guys this time because this was not an easy mold and you guys responded doing another excellent job as usual.”
