• Chassis and Frames: Robust structural elements for equipment, machinery, and electronic devices, providing foundational stability.
• Panels and Covers: Custom access panels, control panels, and protective covers designed for functionality, user interface, and environmental sealing.
• Shielding Components: Specialized parts for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, critical for electronic device performance.
• Industrial Components: Parts for automation equipment, medical devices, telecommunications infrastructure, and other high-reliability applications.

Our ability to integrate these mechanical components with our electronics manufacturing services under one roof provides a distinct advantage, streamlining your supply chain and reducing the complexities often associated with multi-vendor projects.

Materials and Tolerances

Material selection is a critical factor in the performance and longevity of custom sheet metal parts. Four Points Platinum works with a comprehensive range of materials, advising clients on the optimal choice based on application requirements, environmental conditions, and cost-efficiency. Common materials include:

• Aluminum Alloys (e.g., 5052, 6061): Valued for their lightweight properties, corrosion resistance, and excellent strength-to-weight ratio. Ideal for aerospace, electronics, and portable equipment.
• Stainless Steel (e.g., 304, 316): Chosen for superior corrosion resistance, high strength, and aesthetic appeal. Frequently used in medical, food processing, and marine applications.
• Cold Rolled Steel (CRS): A cost-effective option offering good formability and strength, often used when painting or plating is required for corrosion protection.
• Galvanized Steel: Provides enhanced corrosion resistance due to its zinc coating, suitable for outdoor or humid environments.
• Copper and Brass: Utilized for their electrical conductivity, thermal properties, and aesthetic qualities in specific applications.

Our precision sheet metal fabrication capabilities allow us to achieve tight tolerances, typically within ±0.005 inches (±0.127 mm) for critical dimensions, depending on material thickness and part geometry. This level of precision is crucial for ensuring proper fit, form, and function, especially in assemblies where mechanical and electronic components must integrate seamlessly. We employ advanced inspection techniques and quality control protocols throughout the manufacturing process to verify dimensional accuracy and material integrity.

Manufacturing Processes and Capabilities

Four Points Platinum utilizes a suite of advanced sheet metal fabrication processes to produce custom parts efficiently and accurately:

• CNC Punching: High-speed, automated punching for creating holes, cutouts, and forms in sheet metal with excellent repeatability.
• Laser Cutting: Precision laser cutting for intricate geometries, complex profiles, and high-accuracy cuts on various material thicknesses. This method minimizes material distortion and provides clean edges.
• Bending and Forming: State-of-the-art press brakes with multi-axis control for precise bending and forming operations, creating complex 3D shapes from flat sheet metal.
• Welding: TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding capabilities for joining components, ensuring strong and durable seams for structural integrity.
• Hardware Insertion: Automated and manual insertion of various hardware components, including standoffs, fasteners, and captive screws.
• Finishing Operations: A range of finishing options, including deburring, grinding, graining, and preparation for painting, powder coating, or plating. While we do not perform these finishing processes in-house, we manage trusted partners to provide a complete solution.

Our integrated facility allows for efficient workflow between these processes and subsequent assembly stages, reducing lead times and improving overall project coordination.

Design for Manufacturability (DFM) Advisory

Early engagement in the design phase is paramount for optimizing sheet metal part manufacturability, cost-efficiency, and performance. Four Points Platinum offers comprehensive Design for Manufacturability (DFM) advisory services. Our experienced engineers collaborate with your design teams to:

• Optimize Part Geometry: Suggest modifications to part design that simplify fabrication, reduce material waste, and improve structural integrity without compromising functionality.
• Material Selection Guidance: Provide expert recommendations on the most suitable materials based on application requirements, environmental factors, and budget constraints.
• Tolerance Analysis: Review and advise on appropriate tolerances to ensure functional fit and assembly while minimizing manufacturing costs.
• Process Selection: Guide the selection of the most efficient and cost-effective fabrication processes for your specific part requirements.
• Cost Reduction Strategies: Identify opportunities to reduce manufacturing costs through design adjustments, material optimization, and process efficiencies.

This proactive approach helps mitigate potential manufacturing challenges, accelerates time-to-market, and ensures that the final product meets all performance expectations.

Lead Time Considerations and Inventory Programs

Understanding the critical nature of lead times in modern supply chains, Four Points Platinum is structured to offer responsive manufacturing solutions. Lead times for custom sheet metal parts are influenced by several factors:

• Design Complexity: More intricate designs requiring multiple operations or specialized tooling may extend lead times.
• Material Availability: Sourcing of specific or specialized materials can impact the overall schedule.
• Order Volume: Larger production runs typically have longer initial setup times but can achieve economies of scale.
• Current Production Load: Our team works diligently to schedule projects efficiently, providing realistic timelines.

To support production continuity and supply chain security for our OEM clients, we offer flexible blanket-order inventory programs. These programs allow for scheduled deliveries of custom sheet metal parts over an extended period, based on forecasted demand. Benefits include:

• Reduced Lead Times: Parts are produced and held in inventory, ready for immediate shipment as needed.
• Cost Savings: Volume-based pricing can be secured for larger blanket orders.
• Inventory Management: We manage the inventory, reducing your warehousing costs and risks.
• Production Stability: Ensures a steady supply of critical components, minimizing disruptions to your assembly lines.

These programs are particularly beneficial for clients with consistent, ongoing demand for custom sheet metal components, providing a reliable and predictable supply chain solution.
