At SYM Precision Machining, we understand that proper packaging is crucial for protecting your precision machined parts during transportation. To ensure that your products arrive at their destination in perfect condition, we follow a meticulous packaging process that accounts for the material, shape, and size of the parts. Below is our comprehensive guide to effective packaging for precision machined parts, with a focus on protecting the parts, reducing transit costs, and ensuring safety.

Select the Right Packaging Materials

The choice of packaging material is vital in protecting precision machined parts during shipping. We use environmentally friendly and clear materials to maintain visibility and prevent contamination. Our standard materials include: PE bag and film, MG Tissue Paper, EPE foam and bubbles film, cardboard box, PET blister box and Ply-wood crate, etc. 

These materials ensure that parts are not only protected but also stay free from moisture, dirt, and other contaminants that could damage the surface quality.

Find a correct packing method:

1. Keep the Product Clean

• Wear Gloves: To avoid contamination from oil, dirt, or fingerprints, we always handle machined parts with clean gloves.
• Individual Protection: Wrap parts in PE bags or MG tissue paper to protect the surface from any external contamination. This layer serves as a shield against dust, dirt, and moisture.
• Avoid Direct Contact with Bubble Film: While bubble film is effective for cushioning, do not pack parts directly in bubble film. Doing so can leave bubble marks or impressions on the surface of the parts. Always use PE bags or MG tissue paper as a protective layer before using bubble film.

2. Packing Method for Different Materials

• Carbon Steel Parts: Carbon steel is prone to rust and requires special attention to prevent corrosion.
  • Dip in Anti-Rust Oil: To protect against rusting, dip carbon steel machined parts in anti-rust oil before packaging.
  • Use PE Bags: After dipping in oil, wrap the parts securely in PE bags to protect them from moisture and environmental factors.
• Large Parts: Larger machined parts require more flexible packaging.
  • Use PE Film: For large parts, PE film is an ideal choice as it can wrap around irregularly shaped components and provide a good level of protection during transit.
• Mixed Packaging: When shipping or packagingprecision machined parts of multiple materials.
  • Aluminum parts and plastic parts should always be placed on top, steel machined parts placed at the bottom of the box.
  • Light partplaced on top, heavy parts should always be placed at the bottom of the package to ensure stability and to prevent lighter parts from being crushed or deformed.

3. Packing Method for Different Shapes of Products

• Small, Complex Parts: Mass-produced small and complex machined parts require more tailored packaging solutions.
  • Blister Boxes or EPE Foam Boxes: Use blister boxes or EPE foam boxes for these types of parts. These packaging options provide extra protection and help keep parts secure, preventing any shifting during transport.
• Heavy or Bulky Parts: For heavy parts, the packaging needs to be robust to ensure safety during shipping.
  • Plywood Crates: For machined parts that weigh more than 15kg, we use plywood crates. These crates offer maximum protection for heavy or fragile components and ensure safe handling during transportation.
• Mixed Packaging: When dealing with parts of different shapesor significant size differences. The main concern is preventing abrasion, scratching, deformation, or improper alignment when parts come into contact with each other.
  • Sheet metal partsare typically thin, flat, and more vulnerable to bending or warping than solid, bulky metal parts. Placing them at the top of the package prevents heavier, more rigid parts from pressing down on them. Or create separate layers between sheet metal and other machined parts, using cardboard dividers or foam sheets to avoid direct contact between parts with differing shapes and sizes.
  • When parts have large dimensional differences, particularly in height, width, or shape, they should not be placed together.Using separate boxes for different groups of parts.

By following these detailed packing methods, we ensure that SYM Precision Machining provides you with the highest level of protection for your machined parts. Each part is packed in a way that suits its material, shape, and weight, ensuring safe arrival at your destination without damage.

Safety and Transportation Considerations for Precision Machined Parts

At SYM Precision Machining, we consider several key transportation safety factors when packaging and shipping your products to ensure they arrive in perfect condition and comply with transport regulations.

1. Weight Limitations for Packaging

• Cartons: To prevent overloading and ensure safe handling, we limit the weight of each carton to 15kg. This weight limit helps avoid the risk of damage during loading, unloading, and transport, ensuring that the parts are handled with care and reducing the risk of breakage.
• Pallets/Plywood Boxes: For larger or heavier shipments, the weight limit per pallet or plywood box is typically set at 200kg. This ensures that the packaging can withstand the weight during transit, providing both protection for the parts and compliance with transport regulations.

2. Full Filling of Empty Spaces

• Prevention of Shifting: To prevent the machined parts from shifting or being damaged during transportation, it is essential to fill any empty space inside the packaging. By using protective materials like foam, air cushions, or other fillers, we ensure that the parts stay securely in place, minimizing the risk of damage due to movement during transit.
• Maximizing Protection: Properly filling the empty space also prevents parts from colliding with one another, which could lead to scratches, dents, or other forms of damage. This is particularly important for smaller or more delicate components.

3. Consideration of Package Volume to Save Transit Costs

• Optimizing Package Size: It’s not just about protecting your parts—it’s also about optimizing the volume of the package to help reduce transit costs. When packing, we carefully consider the size and shape of each item to avoid excessive unused space that would otherwise increase shipping fees. By packing products efficiently, we can help reduce your shipping costs without compromising the safety or integrity of the parts.
• Space Optimization: In cases where multiple parts are being shipped, we strive to group them together in a way that makes the most efficient use of available space, while ensuring product safety,thus reducing the overall volume of the package and keeping shipping costs as low as possible.
