Creating D-type rubber fenders involves a combination of material science, engineering precision, and design expertise. Here's a closer look at the craftsmanship process involved:

Design and Planning: The process begins with the design phase. Engineers and designers work on blueprints and specifications for the D-type rubber fenders. Factors such as the expected vessel size, berthing energy, and environmental conditions are taken into consideration.

Material Selection: The choice of materials is critical. D-type rubber fenders are typically made from high-quality, marine-grade rubber compounds. These compounds are chosen for their durability, resistance to abrasion, and resistance to harsh marine environments, including UV exposure and seawater.

Compound Mixing: The selected rubber compounds are mixed according to precise formulations. This process ensures that the rubber material possesses the necessary properties, including resilience, hardness, and resistance to environmental factors.

Mold Creation: D-type rubber fenders are crafted using molds that have the desired 'D' profile. These molds are created using steel or other suitable materials. The molds are designed to shape the rubber material into the correct form and dimensions.

Vulcanization: The rubber material is placed into the molds and subjected to a vulcanization process. Vulcanization involves heat and pressure to cure the rubber, creating a strong, resilient, and durable material. This process is critical for the rubber fender's performance and longevity.
