Plastic Injection Molding

What is Thermoplastic Injection Molding?

Plastic injection molding shapes plastic parts by injecting molten plastic under high pressure into a cooled metal mold. The mold cavity determines the final shape, and the process allows for mass production of complex and precise plastic components. ASH is known for an engineering approach to this type of molding and revolutionized the short run, pre-production stage with ASH SUPERMOLD PROGRAM.

Metal Injection Molding (MIM)

What is Metal Injection Molding?

MIM works similar to the other injection molding processes - powdered metal is combined with a binding material and then injected into a mold where it's left to form and curate. After sintering out the binder, the end result is a metal part. The process is ideal for complex metal parts where CNC Machining is cost prohibitive. Here's a closer look at the ASH MIM process:

What is Metal Injection Molding?

Rotational molding, or rotomolding, creates hollow plastic parts by heating and rotating a mold filled with powdered plastic. This slow process ensures even distribution of the material, making it ideal for large, one-piece items like kayaks with consistent wall thickness. Prodcuts can be foam filled for strength and buoyancy. Here's a closer look at the ASH Rotomolding process:

Silicone Injection Molding

What is Liquid Silicone Molding? (LIM)

Liquid silicone molding (LSR) shapes complex and detailed parts by injecting liquid silicone into a heated mold. This versatile technique allows for intricate designs and smooth finishes, making it ideal for products like baby bottle nipples and medical components. Here's a closer look at the ASH LIM process:
