Finishing
There are a limitless number of secondary operations that can be performed on a blow-molded part to meet the needs of the finished product. Drilling, sawing, milling, cnc routing, die cutting, punching, riveting, screwing, sonic, spin or heat welding, and surface treating are common operations. Nearly any secondary step can be performed economically if the right equipment is available. Custom-Pak provides a variety of secondary operations equipment at no charge.

Decorating molded parts requires planning in the design stage. Texture is commonly applied to mold surfaces. Blow molding textures are typically etched .008" to .012" deep in the mold surface (much deeper than injection molding). Draft may be needed to allow the texture to form and still release from the mold. For heat transfer or hot stamp decorating, the part design must provide a means to support the tonnage of the stamping process. For in-mold labels, magazines to hold the labels and mold surface locators must be prepared. For embossed plaques, the attachment method should be included in the part design. There are many ways to get the appearance that you want in your blow molded parts. We can help you make sure your design will look great long after the consumer has made their purchase.
