Injection Molding


Custom Precision Thermoplastic Injection Molding from Aline Components, Inc.

The primary process for manufacturing custom plastic parts and components is thermoplastic injection molding. The primary source for your injection-molded products is Aline Components, Inc. Although custom plastic molding differs from one product manufacturer to another, the principle of applying heat and pressure to form plastic parts or components is a method that is synonymous across the mold making industry. When you choose Aline, Pennsylvania's leading plastic injection molding company, you are guaranteed professional quality assurance standards, the latest in technological equipment, and innovative, cost-efficient manufacturing techniques.
Benefits of Thermoplastic Injection Molding
  • Increased production rates
  • Decreased labor costs
  • Repeatable tight tolerances
  • Increased range of materials
  • Reduced scrap loss
  • Minimized finishing

Known as a versatile and economical material, plastic can be used in a variety of applications. Of all the available plastic processing methods, thermoplastic injection molding is the most widely used among the broadest spectrum of markets. Since 1965, we have maintained a leadership position by offering superior plastic injection molding services to customers based nationally and regionally in Pennsylvania, New Jersey, New York, Delaware, and Maryland. At Aline, simple to complex geometries are possible and limited only to the mold manufacturability. Tooling may be expensive, but cost-per-part remains low.

Aline's Design Considerations for Custom Plastic Injection Molding

To minimize sinking, warping, residual stresses, and improve mold fill and cycle time, we use uniform wall thickness.

To achieve a minimum of one material thickness at the inside corner radius, we allow a generous radius at all corners.

To ensure rapid cooling, short cycles times, and minimum shot weight, we utilize the least thickness compliant with the process, thermoplastic material, or product design requirements.

To facilitate easy withdrawal from the mold, we design parts that feature a draft (taper) in the direction of mold opening or closing.

To improve part stiffness in bending, we use ribs or gussets.
