China Outer Casing OEM/ODM

What Types of Outer Strapping Are There?

Outer strapping is used widely in packaging, logistics, and industrial settings to secure goods during storage or transportation. Depending on the load requirements and working conditions, several types of strapping are commonly applied.

Steel Strapping

Known for its high tensile strength and resistance to impact.

Often used for heavy-duty applications such as bundling construction materials, steel coils, or large machinery.

Although strong, it is heavier and can corrode if not treated.

Polypropylene (PP) Strapping

Lightweight and cost-effective.

Suitable for lighter loads, such as cartons, newspapers, or parcels.

Easy to apply and often used in small to medium-scale packaging operations.

Polyester (PET) Strapping

Provides a balance between strength and flexibility.

Common in industries such as beverages, tiles, and medium-weight pallets.

Maintains tension over time and resists stretching.

Composite and Woven Strapping

Made from polyester fibers, often coated for added durability.

Strong and safer to handle compared to steel.

Frequently used in securing heavy loads for export or long-distance shipping.

The choice of outer strapping depends on whether the priority is strength, cost efficiency, or safe handling. Industries select materials according to load weight, environmental exposure, and transport requirements.

What Materials Are Used for OEM/ODM Outer Casings?

OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) casings are protective housings that cover and safeguard devices or machinery. The choice of material directly affects durability, cost, and appearance.

Plastics (ABS, Polycarbonate, and PP)

Widely used due to their versatility, lightweight nature, and cost-effectiveness.

ABS is valued for toughness, while polycarbonate provides impact resistance and clarity.

These materials are common in consumer electronics, appliances, and automotive components.

Metals (Aluminum, Stainless Steel, and Magnesium Alloys)

Metals are chosen for strength, durability, and heat resistance.

Aluminum is popular in electronics for its lightweight and corrosion resistance.

Stainless steel offers toughness and is used in heavy-duty or aesthetic casings.

Magnesium alloys are used where both strength and reduced weight are required.

Rubber and Silicone

Often used for shock-absorbing casings or protective covers.

Provide grip, water resistance, and cushioning.

Found in handheld devices, outdoor tools, or automotive parts exposed to vibration.

Composite and Hybrid Materials

Combine plastics with fiberglass or metals to balance strength and weight.

Applied in specialized areas such as aerospace, high-end electronics, or protective automotive panels.

OEM/ODM casing materials are selected according to their function—lightweight plastics for affordability, metals for durability, and composites for specialized requirements. The choice often reflects a balance between performance and cost.

What Are the Production Steps for Nut Hex for Automotive and Motorcycles?

Hexagonal nuts are essential fastening parts that connect with bolts in vehicles. Their production involves a series of steps designed to ensure strength, precision, and reliability.

Raw Material Selection

Typically medium or high carbon steel, stainless steel, or alloy steel.

Material must provide a balance between strength and corrosion resistance.

Cutting

Steel rods or wires are cut into short pieces that will serve as nut blanks.

Cutting ensures consistency in size before shaping.

Forging

Nuts are shaped into their hexagonal form by either cold forging (at room temperature) or hot forging (at elevated temperatures).

Forging establishes the overall structure and the central hole.

Threading

Internal threads are added through cutting or rolling.

Thread rolling is often preferred because it strengthens the material.

Heat Treatment

The nuts are heated and cooled under controlled conditions to improve hardness and toughness.

This step ensures performance under stress and vibration.

Surface Treatment

Protective coatings such as zinc plating, phosphate, or nickel are applied.

These finishes prevent corrosion and improve service life.

Quality Inspection

Nuts are tested for dimensional accuracy, thread quality, and strength.

Only parts that meet automotive and motorcycle standards proceed to packaging.

Summary: Nut hex production is a precise process, with each step contributing to the component’s safety and performance in demanding applications.
