Categorias: , Marcação:

Our high-quality parafusos de automóvel are designed to meet the demanding needs of the automotive industry. Manufactured with precision and durability in mind, esses parafusos de automóvel are ideal for a wide range of applications, from engine assembly to bodywork. Made from premium materials, they offer superior strength, Resistência à corrosão, and long-lasting performance. Whether you’re restoring a classic car or working on modern vehicles, our bolts provide the reliability you can trust for every project.

Raw Material Selection

High-strength steel wire rods (Por exemplo, aço carbono, liga de aço, or stainless steel) are selected based on the required mechanical properties and application.

Wire Drawing & Corte

Steel wires are drawn through dies to reduce to the desired diameter, then cut into precise lengths for each bolt size.

Cold Heading / Forging

The bolt head is formed using high-speed cold forging machines. This process increases the material’s strength through strain hardening.

Thread Rolling

Threads are formed by rolling rather than cutting, which, in turn, enhances thread strength and improves fatigue resistance.

Tratamento térmico

Bolts undergo heat treatment, including quenching and tempering, to achieve the required hardness, strength, and toughness, ensuring optimal performance under stress.

Tratamento de superfície

Various coatings are applied to improve corrosion resistance and appearance, incluindo:

  • Batinho de zinco (blue/white/yellow)
  • Dacromet coating
  • Phosphate coating
  • Óxido preto

Inspection and Testing

We perform dimensional checks, hardness testing, tensile strength testing, and thread gauging to ensure quality. Adicionalmente, some bolts undergo fatigue and salt spray tests for further durability assessment.

Sorting and Packaging

Automatic optical sorting machines ensure 100% defect-free output. Bolts are then packaged and labeled for delivery.

Soluções personalizadas: Our CNC bolts offer tailored non-standard customization to meet specific requirements, ensuring a precise fit for unique applications. This product is ideal for users who need bespoke fasteners for their projects.

Durable Materials: The product is available in various materials, including steel, alumínio, copper, and stainless steel, providing a durable and long-lasting solution for general industry applications.

Multi-Functional: The CNC bolts cater to different needs by offering various head types and surface treatments, such as zinc plating and plain finish, to suit diverse user preferences and requirements.
