Blow Molding
NEXAMS Leading the Way in Blow Molding for Plastic Manufacturing Across Multiple Industries
Blow molding is a highly efficient manufacturing process used to create hollow plastic products by inflating a heated plastic tube, known as a parison, inside a mold to form plastic containers and plastic products. At NEXAMS, we plan each program with empathetic, ethical decision-making so that real constraints—budget, timelines, and sustainability—are respected; we also coordinate transparently with trusted Vendors while providing human-like Support that keeps communication clear, options balanced, and trade-offs explained before you commit.
Our teams specialize in solutions tailored from packaging to medical devices, using advanced CNC machining and injecting molding integration to achieve repeatable quality. We collaborate closely with experienced Manufacturers to validate tooling, stabilize cycle times, and document process windows, ensuring that every plastic bottle, plastic tote, poly tank, or PET component meets specifications with traceability and care.

Materials Used in Blow Molding
Polyethylene (PE): Workhorse resin for plastic containers, plastic totes, and poly tanks, offering toughness and chemical resistance.
Polypropylene (PP): Rigid, fatigue-resistant choice for hinges and heat-tolerant plastic products.
Polyethylene Terephthalate (PET): Preferred for beverage plastic bottle clarity and recyclability with stretch-blow advantages.
Polyvinyl Chloride (PVC): Utilized for medical and industrial containers where clarity or specific chemical resistance is needed.
Engineering Resins: High-performance blends for demanding automotive or industrial environments.
Recycled Materials: PCR and PIR options incorporated with documented sourcing through an audited Supplier chain.
How Costing Works in Blow Molding
Costing at NEXAMS is project-specific, factoring in design complexity, resin class, production volume, tooling approach, and any secondary operations such as trimming, insertion, or printing. Precision CNC machining shortens tool tryouts and reduces rework, and our quotes include resin consumption models, cycle-time assumptions, and contingency notes so decisions are made with clarity and accountability; ongoing Support covers PPAP/FAI, ramp stabilization, and continuous improvement actions.
