Technology and precision

The core of our expertise

Advanced injection molding solutions

National Molding Italia is specialized in injection molding, co-injection molding, and overmolding. This includes overmolding between plastic materials (typically plastic-rubber) or overmolding of metal components, utilizing advanced 2K technology (bi-injection molding).

The company’s advanced machinery, automated feeding systems, and measuring technologies have enhanced production efficiency and service offerings, ensuring maximum quality from design feasibility to product realization.

Quality control system

National Molding Italia guarantees superior quality by utilizing a specially developed statistical process control system that monitors the production cycle in real-time.

Quality begins at the design stage, continues through the first prototypes, and extends to full production, with continuous monitoring across all production shifts and processing cycles.

Materials and performance

Engineering strength and versatility

Acetal polymers

Acetal, referred to as polyacetal and polyoxymethylene (POM) is a semi-crystalline, low friction engineering thermoplastic, offering exceptional strength, stiffness, and stability. This versatile material is characterized by:

Wear resistance and longevity
Impact resistance
High elasticity and stress resistance
Heat resistance
Cehemical resistance.

Nylon polymers

Nylon is a family of versatile synthetic polymers, known as polyamides, characterized by high strength, durability, and low friction. At National Molding, nylon is available in three types:

Nylon 6 – High strength, good chemical resistance, commonly used in applications that require durability and toughness.
Nylon 66 – High melting point, good dimensional stability, and excellent wear resistance.
Nylon 12 – Flexible and impact-resistant, good chemical resistance, and low moisture absorption.

Additional Polymers

Polycarbonate

Polycarbonate (PC), a technical amorphous thermoplastic material:

transparent
hygroscopic (absorbing moisture)
with an excellent impact resistance
with a good dimensional stability
with a high temperature resistance
ideal for products requiring durability and toughness.

Polybutylene therephtalate

Polybutylene therephtalate (PBT), a semy-cristalline thermoplastic engineering polymer:

strong and rigid
resistant to chemical agents (oils, greases, and solvents)
with a low moisture absorption
ideal for components subject to stress.

Polypropylene

Polypropylene (PP), a thermoplastic polymer slightly harder than polyethylene:

lightweight with a lower density than water
with an excellent resistance to a variety of chemical agents
used at high temperatures (up to approximately 100 °C-120 °C) without losing its mechanical properties.
fully recyclable
ensuring durability in applications requiring mechanical strength.
