- Insert Molding
The Plastics Group does insert molding using many different types of inserts – from polypropylene mesh for strainers to tungsten penetrators for US Munitions. It can be one simple stainless steel knob insert to multiple inserts molded in place each shot.
Currently we do insert molding for Beverage and Industrial Fluid Handling, Defense, Electronics, Industrial Equipment and commercial products.
- Metal to Plastics Conversion
- Over the years we have provided major cost savings for our customers by engineering for them metal to plastic conversion for their product. Not only was there less cost, but also less weight and improved efficiency due to the design for manufacturability – supporting them in their assembly process. In the example shown, we have converted it from a metal to a clear resin.
- Mold Steels
In an age that demands high productivity in manufacturing, there is no substitute for high quality molds in your injection molding process. Given the wide variety of mold steels available today, proper selection must take into account not only price and traditional practice but why they are used. In order to make the proper selection, one must understand the multiple demands that are placed upon mold steels, depending on the specific application.
- Part Design
- Our Plastic Part Design engineers will design your part using the latest technology from concept to finished product. We use modern platforms of SolidWorks and other design software. We are able to do mold flow analysis to support your engineering needs. We’ll design a plastic part to meet the needs and specifications you require. We can handle defense specifications, FDA, UL, ASTM requirements. Our Plastic Part Design Engineers will help you choose the plastic (we have a database of 30,000 materials) and provide prototypes for testing, and manufacture your newly designed part.
- Retainer Ring
The part shown is used in Automated Assembly of Hydraulic Valve Spools – Previously our customer used another manufacturing method to manually attach sections of the spool. By changing to this part - .580” diameter rings with .020” wall and v-groove designed to break at a predetermined PSI - they experienced a 60% increase in yield and throughput. This is another example of solving the customer’s challenge with engineering and metal to plastic conversion.
Rotor moving and stationary: Overmolding of a spider gear with .080" to 0.70" wall thickness in peek material with less than .009" deflection.
- Secondary Services
In mold operations such as engraving, inserted nameplates, and labeling. After mold operations such as inserts, machining, drilling, reaming, and more. Assembly such as ultrasonic welding, adhesive & solvent bonding, and mechanical assembly.
- Two-Stage Molding
We provide Two Stage Molding (also known as Over-molding) for applications that call for two materials in the product. This completely replaces mechanical or adhesive bonding. The example shown is an electrical connector – we also provide Two Stage Molding for medical and consumer products.
