Product Description

Custom Welded Aluminum Rotomolding Boat Mold

Integral Reinforced Frame Rotational Mould for HDPE Plastic Fishing Boat Manufacturing

Product Overview

The SUNMORE Custom Welded Aluminum Rotomolding Boat Mold is a large integrated aluminum alloy rotomolding mold independently developed for mass production of HDPE plastic fishing boats, aquaculture work boats, water patrol boats, and leisure plastic boats. The entire mold features thick aluminum plate full argon arc welding combined with an integral multi-point reinforced support frame to effectively resist high-temperature rotary stress and prevent deformation during long-term production. The mirror-polished inner cavity ensures finished plastic boats have smooth surfaces without burrs. We offer full OEM & ODM customization including boat length, hull radian, rib mold positioning, and anti-collision thickening areas.

Key Features & Benefits

Thick Aluminum Plate Full Welded Mold Body: Industrial thickened aluminum alloy plate with integrated argon arc welding ensures uniform heat conduction during oven heating, preventing local overheating deformation and maintaining consistent dimensional tolerance across batch production.
Integral Multi-Point Reinforced Support Frame: Independent aluminum alloy reinforced support brackets at the bottom and sides feature multi-point stress dispersion design to offset torsion force from high-speed rotation, preventing sagging or warping over thousands of production cycles.
Mirror Polished Inner Cavity: Precisely polished inner wall creates smooth, delicate plastic boat hulls without welding lines or pits, reducing secondary grinding and trimming procedures while improving production efficiency.
Customizable Hull Structure Mold Inserts: Prefabricated integrated mold lines for hull reinforcing ribs and anti-collision thickening areas according to customer ship drawings enable one-step streamline shape formation without later modification.
Complete Customization for Fishery & Water Vessel Projects: Adjustable boat mold length, redesigned hull streamline radian, and customizable anti-collision thickening positions to meet aquaculture, patrol, and leisure ship production requirements.

Frequently Asked Questions

Will this large aluminum boat mold deform after long-term high-temperature rotary production?

The mold body uses thick aluminum full welding plus integral multi-point aluminum support frame, which evenly disperses high-temperature rotation torsion force, effectively avoiding permanent sagging and deformation of the mold after long-cycle mass production.

Does the finished plastic boat need manual grinding and trimming after rotomolding with this mold?

The inner cavity is processed by high-precision mirror polishing, the hull surface is smooth without burrs and welding lines after demolding, reducing post-processing polishing work.

What customization support can be provided for plastic boat factory bulk mold orders?

We can adjust the overall length of the boat mold, redesign the hull streamline radian, add built-in reinforcing rib mold lines and expand anti-collision thickening areas according to customer demands.
