Custom Injection molding, any Quantity

Overview:

 

Quality Plastics produces a wide range of custom injection molded parts out of an extensive variety of plastic resins.  We will procure and mold any available material that you spec.  We currently run various grades of polypropylene, polyethylene, ABS, PVC, polycarbonate, nylon, UHMW, ASA, TPE, and continue to add to the list as needed.

No job is too small - we accommodate any quantity you may need, from lower volume short runs to higher volume mass quantity runs.

All parts are made in our own facility located in Ohio, USA.  This gives us full control over quality, allows us to turn orders around quickly and gives us the ability to address any questions or quality concerns in a timely manner.  All molds are safely stored in our facility.

Our molding machine fleet ranges between 55-1300 tons.  This wide range provides us a great deal of flexibility in part sizes we can produce, varying from very small all the way up to 12.6 pounds.  Machines currently in service are:

  • (2) 55 ton Cincinnati Milacron - 1.08 and 2.3 oz max part weight

  • (2) 85 ton Cincinnati Milacron - 4.44 oz and 6 oz max part weight

  • 110 ton Cincinnati Milacron - 5 oz max part weight

  • 220 ton Cincinnati Milacron - 17 oz  max part weight

  • 310 ton Toshiba - 24 oz max part weight

  • (2) 500 ton Toshiba - 63 oz max part weight

  • 550 ton Cincinnati Milacron - 76 oz max part weight

  • (2) 725 ton Cincinnati Milacron - 140 oz and 179 oz max part weight

  • (2) 1300 ton Engel - 202 oz and 264 oz max part weight

Advantages of Injection Molding:

  • Piece Price: pricing of injection molded components is typically significantly lower than other manufacturing processes, especially with high production quantities.

  • Scalability:  Plastic injection molding can be the ideal process for any quantity, ranging from several hundred piece low-volume runs to machines running non-stop while producing millions of parts a year.

  • Efficiency: with properly designed tooling, injection molding can be a very efficient process with less waste than other manufacturing options.

  • Strength of parts: with careful material selection and proper design, injection molded parts can be just as strong, if not stronger than, machined parts. 

  • Accuracy: with precision machining of the mold and a finely tuned molding machine, parts with high accuracy can be re-produced thousands of times over.

  • Design flexibility: the injection molding process is commonly used to reduce overall product costs by creatively designing parts to reduce number of components.  This also typically results in quicker assembly of components.

Things to Consider During an Injection Molding Project:

  • Part:

    • Part design - must be manufacturable with proper draft angles

    • Strength requirements

    • Plastic material selection and cost

    • Color

    • Surface finish requirements

    • Estimated annual usage (EAU)

  • Tool:

    • Tool material

    • Tool cost

    • Number of cavities

    • Gate type and location

    • Hot or cold runners

    • Venting

    • Part ejection

    • Any necessary surface coatings and plating

  • Prep and packaging:

    • Secondary machining or part prep operations

    • Assembly operations

    • Packaging requirements
