Plastics Manufacturing & Injection Molding

Plastics injection molding manufacturers produce plastic parts and products by injecting molten plastic into molds for product manufacturers and businesses.

With plastic components used across all industries, molders generate revenue of $450,000-$1,500,000+ annually with profit margins of 25-40% through production contracts.

The business requires injection molding machines (starting from $50,000 to $300,000+ each), molds (tooling), plastic resins, facility with appropriate utilities, and trained operators.

Services include custom part production, low to high volume runs, mold design consultation, and sometimes tooling.

Pricing includes tooling costs ($5,000-$100,000 per mold) plus per-part costs.

Success factors include quality consistency, process optimization, ability to work with various resins, and maintaining tight tolerances.

Common clients include product manufacturers, automotive suppliers, medical device companies, and consumer goods brands.

Most molders specialize by industry or part size/complexity.

The business requires significant capital but offers recurring production revenue.

Marketing focuses on demonstrating molding capabilities, quality systems, capacity, and industry certifications.

With manufacturing continuing strong in 2025, injection molding offers opportunities for entrepreneurs with plastics expertise willing to make substantial equipment investment.
