Injection Molding

Prototype injection molding is a specialty service, combining rapid prototyping techniques with more traditional plastic injection molding processes.

Dinsmore & Associates uses rapid tooling in conjunction with plastic injection molding to quickly create any quantity of thermoplastic parts. This fast prototyping injection molding service creates injection-molded plastic parts for a variety of uses. With press sizes ranging from 75 to 150 tons, Dinsmore & Associates can meet your injection molding part needs from 25 parts to high-volume production runs.

For the prototype injection molding process, any thermoplastic materials, including fiberglass-filled materials, can be used. In some cases there are specialty materials that the customer requires that can only be met with our injection molding process. Dinsmore & Associates specializes in plastic injection molding and prototype engineering or “DFPT” design for prototype tooling which assists with common or special needs.

INSERT MOLDING

Dinsmore & Associates offers full capabilities in insert molding, starting with manual loading of metal inserts for conventional, hydraulic and vertical shuttle press molding. Operator assisted, semi-automated loading of multiple part strips using offline loading fixtures is used in many tight tolerance, mid-range volume applications. Automated insert in a continuous reel-to-reel molding process is used when high volume precision molding is required.

Insert molding provides customers with a lower cost alternative to other manufacturing methods by reducing assembly and labor and increases product reliability as parts are secured tightly into thermoplastic to provide added strength by consolidating parts.

Dinsmore & Associates has considerable experience in developing new product designs, as well as transferring existing tooled programs. We will support you on your easiest part configurations to the most complex moldable geometries. With our in-house CNC machining capabilities, we can even provide solutions to save tooling expense or to create non-moldable geometries.

OVER-MOLDING

Over-molding is becoming increasingly important, not only to esthetically enhance a product with color, but also to provide function, such as a softer, non-slip handle grip and shock absorption on consumer products. Dinsmore & Associates provides over-molding in a variety of applications from consumer household and cosmetic products to dental and medical devices.

Over-molding is the process where one plastic material is injected and molded over a second plastic material. The over-molded part will form a strong chemical bond, in some instances and will be mechanically aided in others to maintain its strength in the end-use application. Applications include soft touch handles and grips to improve tactile properties, impact resistant surfaces to increase durability, or to differentiate the end product and improve aesthetics.
