Specialty high performance molding capabilities

We handle a variety of specialty molding processes, including conventional custom molding, decorative and cosmetic molding, miniature molding, over molding, and insert molding.

Plastic injection over molding

Over molding is a process that manufactures two or more materials and/or colors within the same product or part. In technical terms, this means multiple materials are injected at two different points or more within the injection mold to create one final part. This process can be utilized across singular or multiple cavities within the injection molding process.

The injection over molding process is ideal for specialty items or products that can eliminate costly secondary processes or assembly. Examples are:

  • Gaskets, seals or sealing mechanisms
  • Soft touch products
  • Functional parts
  • Acoustic dampening elements
  • Vibration absorbing products
  • Decorative or advanced aesthetics
  • Permanent descriptions or identifications
  • Enclosure of multi-components products

Insert molding

Insert molding lowers the cost of end use products and subassemblies by reducing or eliminating secondary assembly operations and labor costs through the introduction of components into the plastic molding process. This process combines plastic resin with materials like metal stampings, electromechanical parts, machined metal parts, filters, gaskets, and more into a single viable product.

Our custom insert molding services and capabilities include:

  • Automated, semi-automated, and manual component insertion
  • Post molding secondary operations for electrical testing, machining, bonding, etc.
  • Post manufacturing quality inspection capabilities
  • Design of manufacturability for multi-components
  • Custom designed tooling and fixturing
  • Advanced materials selection

Decorative and cosmetic molding

Decorative molding has been a growing industry requirement within the plastics industry for several years, and Aztec Plastic has been at the forefront of this process. It is used when a product requires extremely high aesthetics or visually appealing external features. The decorative features of a product may include visual aesthetics, special textures, lens quality requirements, scratch free surfaces, and unique colors, materials, or packaging.

Aztec Plastics has over 50 years of experience with the following processes which are critical to producing excellent quality decorative molding:

  • Advanced decorative applications
  • Specialized material selections
  • High end manufacturing processes
  • Two shot over molding processes
  • Color printing
  • Pad printing
  • Texturing
  • Assembly
  • Specialized packaging and kitting solutions
  • Labeling

In mold decorating

In mold decorating (IMD) or in mold labeling is a highly unique and specialized method of injection molding which introduces a label or applique into the injection molding manufacturing process. This label or applique can be decorative or instructional and becomes a semi-permanent, imbedded component of the molded object.

The in mold decoration process injects molten material or plastic resin into a specially designed tool in which the label or applique becomes an integral part or attribute of the plastic molded product. This special injection molding process provides increased durability, strength, creative design, decorative, and cosmetic options to the finished goods and products.

Aztec Plastic’s in mold decorating services offer several advantages:

  • Consultative interaction for manufacturability
  • Specialty material selection assistance for resins and applique
  • Automated introduction, placement, and positioning of the applique or label
  • Manual and semi-automated options
  • Early involvement engineering for custom applique or label design

Molded in color and multi shot molding

Molded in color and multi shot molding refer to molding plastic parts with two or more colors or materials in a single injection molding operation and machining cycle. Using this plastic injection molding method, Aztec Plastic can give your product a high quality, long lasting color and finish. The advantages of molded in color and multi shot molding are coloring that can withstand harsh environments, no paint scratching or peeling, no secondary painting, with faster and lower cost part production.

Aztec Plastic can use molded in color and multi shot molding to create a wide variety of plastic products, including:

  • Body panels, fenders, and housings for the automotive industry
  • Recreational and marine vehicle components
  • Plastic parts for agricultural equipment
  • Industrial and consumer appliances
  • Lawn and garden equipment components
