Laser Plastic Welded Automotive Oil Pans, Sumps and Oil Filters
Extremely strong joints without the need for screws or glue
to increase product quality and yield
while reducing weight and complexity
Use of Plastics to Decrease Weight and Improve Margins Over Aluminum and Steel Oil Pans
The use of thermoplastic and composite materials in automotive oil pans, sumps and engine oil filtration is growing as automotive design engineers look for weight savings as a path to increased fuel efficiencies. New engine designs where the oil pan is a structural element of the engine are being developed to reduce vibration and noise. Strong, light weight, reinforced plastics are used in these new engine components. Laser plastic welding is the perfect assembly technique for plastic oil pans and oil filters for added weight savings, reduced bill of materials, stronger bonds and reduced assembly times. Laser plastic welding is used to secure filter media in plastic housings and in subassemblies integrated into the oil pan.
Welding of Engineering Polymers
Laser plastic welding can weld any thermoplastic polymer, including up to 30% glass filled nylons; PA-6, PA-66, PBT, PET, PC, PBT/ABS alloys, and many others.
Major Benefits of Laser Plastic Welding to Assembly Plastic Oil Pans, Oil Filters and Oil Sumps
Laser plastic welding offers a high degree of flexibility to rapidly and inexpensively change over to new designs and adapt to new product form factors by simply changing the tooling and uploading the latest CAD designs into the machine. Laser plastic welding machines are available in the right size to fit your needs with machines to accommodate part sizes from 100 mm x 100 mm to 1,000 mm x 750 mm.
Key Advantages for Laser Welding of Plastic Fluid Components
Laser plastic welding is a particle-free joining process compared to ultrasonic or vibration welding so your assembly process will not contribute to particulate contamination from the manufacturing process.
The dynamic process of quasi-simultaneous welding supplies additional material to the joint, much like a welding rod in metal welding, to create joints that exceed the strength of the molded parts themselves.
Significant Savings on BOM and Labor
The laser plastic welding assembly method allows designs without the need for screws that reduces the bill of materials (BOM) and therefore costs compared to components that are secured with screws. Laser plastic welding is a faster assembly method compared to UV cured adhesives and eliminates the costly maintenance and mess of glue dispensing and curing.
Fast Cycle Times
Depending on the part size, laser plastic welding machines from LPKF has cycle time from a few seconds on small parts (100 mm x 100 mm) to under a minute for large parts (500 x 350 mm).
Laser Welding Machine Configurations
LPKF has a wide range of highly flexible, standardized machines with custom tooling to rapidly change from one part to another with a simple CAD import and quick-change tooling. Laser welding machines come in four different standard sizes to match your part size and budget.
