What We Do – Injection Molding & Toolmaking

J&L Plastic Molding is an ISO 13485:2016 certified tooling and injection molding company with vast prototype and development experience. We help companies – medical device and other industries – learn lessons in the prototype phase to seamlessly transition to production. In one prototype project the tool may convert to production because J&L designs the prototype with the capability to scale to meet production requirements. Another project may focus on running and revising the prototype tool to troubleshoot material selection, processing, part design, market demand and other issues. Knowledge gained from this prototype results in a production tool with proven design, material and process able to meet market demand. No prototype project is the same, J&L will focus our tool design and processing to meet your requirements (not vice versa).

How We Do It

Tooling

First, we ask questions to learn short-term needs and the long-term goals of the project. We review the Part Design, Material Selection and Lead Time Requirements. Based on our findings we develop a quote using J&L’s resources.

What type of Framing System – Based on the specifications of the project J&L will choose the proper Frame System:

  • Master Unit Die (MUD) Frame System allowing the Customers to only purchase the insert mold (cavity). It is not necessary to purchase an entire standard mold frame. Saves time and money.
  • Prototype Plus Frame System developed by J&L Plastic Molding using S-7 steel cavity blocks to fit a standard frame. This standardized system saves time and money with the advantage of meeting production capacity.
  • DME-Style Production Mold Base: Conventional mold base and cavity blocks.

J&L has complete Tooling capabilities in our facility. We build and maintain Tools.

Designing and building the proper tool is the just the beginning of the relationship with J&L.

Injection Molding

We operate in two buildings in Wallingford, Connecticut with 28 injection molding machines ranging from 28 to 385 tons of clamp force, and shot sizes from .6 to 24 ounces. We are proficient at production injection molding, prototype molding and insert molding. We process the full range of performance materials from commodity grades to engineering thermoplastic resins.

Capabilities supporting our Injection Molding Operation

  • Machining: J&L can machine part features as a post-molding operation. We can also machine Plastic, Stainless Steel, Aluminum and Brass parts.
  • Ultrasonic Welding: The application of high-frequency vibrations to two parts by a vibrating tool, known as a “horn.” Welding occurs as the result of heat generated at the interface between the parts or surfaces. It’s fast and efficient.
  • Pad Printing / Plastics Decorating: Pad printing is an offset process. An engraved plate is coated with ink, then squeegeed, leaving wet ink on the plate in the engraved pattern. A silicone pad is pressed onto the plate and rises with the inked image. The inked pad descends onto the plastic component and imprints the image. Because the pad is pliable, it can form around irregular surfaces.
