Plastic Injection Molding
With presses ranging in size from 55 ton up to 950 ton we can make parts small and large. Our experienced team can ensure that you receive quality parts at an affordable price.
Using insert molding, metal parts such as inserts, clips, and terminals, are molded directly into your plastic part. You can avoid expensive secondary operations and get better results. Insert molding gives added strength and increased visual characteristics to the finished product.
Shuttle molding saves you the expense of a large die and provides more flexibility when it can be used. This molding machine provides efficenty by using multiple die halves, allowing for you to load inserts as you mold parts in the other half.
Gas Assist Molding
Gas assist plastic molding allows for the creation of one or more hollow channels in a plastic part during the injection molding process. Some of the benefits to this are less plastic is required, part weight is reduced, increased part strength, and improved visual appearance.
Our ability to use sonic welding allows us join two or more plastic parts together when they are of the same material. Sonic welding uses sound wave energy to fuse the plastic parts together. This means you can avoid the expense, the mess, and the curing times associated with adhesives. Sonic welding is quick, clean, and cost effective.
About H&L Advantage
The real focus is about what that journey has done to make H&L an asset to your company when you need plastic products manufactured.
H&L Advantage began in 1970 with only 3 people and a small office. We served as a sales, design, and engineering firm for manufacturers, to bridge a gap that existed at the time between manufacturers and the customers who wanted and needed their products.
