Injection Molding

Our molding machines range from 55 tons with a 4 ounce barrel capacity up to our 440 ton with 41 ounce barrel capacity. We specialize in tight tolerance molding of engineered thermoplastics, over-molding and insert-molding technology. And In many cases, we can integrate all these processes into a single molded part to help our customers with reduction in assembly time, quantity of operations, and labor requirements.

Our molding machines range from 55 tons with a 3 ounce barrel capacity up to our 440 ton with 55 ounce barrel capacity. We also manage all secondary operation requirements that may be needed to complete your part. Examples of those operations that are available include ultrasonic welding, heat staking, vacuum metallization, EMI shielding, Part decorating (pad print, silk screen, sublimation, paint, emulsion, bath, etc.), Machining/milling, and many types of assembly.

Here at H&H we have 3 Soft wall Modular Clean rooms to provide an economical, versatile solution to clean manufacturing requirements in the medical device, Pharmaceuticals and many other industries.
