How to Protect Plastic Tooling from Damage During Long-Distance Shipping

Long-distance delivery can expose plastic injection tooling to handling and transit risks. To reduce the chance of damage, specify secure packaging suited to the chosen freight route, and verify the mold’s condition before it leaves the supplier. For tooling with precision tolerances as tight as ±0.02mm, inspection records and clear shipment documentation are especially important.

Set Packaging and Shipping Requirements

Ask the supplier to confirm how the mold or plastic products will be packed for the selected transport method. Longterm states that it securely packs molds and plastic products for sea freight, and offers air freight for urgent orders and samples, railway freight for China-Europe routes, and courier services for light, small shipments.

Choose a method based on the route, shipment size, and delivery urgency. Sea freight is suited to bulk orders; air freight can serve urgent shipments and samples; railway freight connects China and Europe with a different balance of cost and transit time; DHL, FedEx, or UPS may suit smaller, lighter consignments.

Verify Tooling Details Before Dispatch

Include the tooling’s technical specifications and condition in the shipment file. Relevant details may include mold base material, cavity steel, runner configuration, precision tolerance, expected mold life, and inspection status. Longterm lists S50C and P20 for mold bases, 718H, 1.2738, and S136 for cavity steel, and both cold-runner and hot-runner configurations. The stated tolerance is ±0.02mm, with a mold life of 50,000 to 1,000,000 shots.

Before dispatch, request the mold trial test record, dimensional inspection results, and a full pre-shipment inspection report. Keeping these records creates a baseline for assessing the tooling after arrival and can help guide any later maintenance.

Match Freight to the Shipment

Supplier Experience and Support

Longterm reports tooling experience across consumer electronics, home appliances, automotive components, industrial equipment, and everyday consumer products. In one project for an Italian manufacturer, the company supplied three electronic housing mold sets for a handheld device. The customer noted accurate dimensions, smooth surfaces, responsive communication, and delivery on schedule. A French consumer electronics project used double-shot overmolding molds; the customer reported good alignment and consistent trial samples.

The company holds ISO 9001:2015 certification covering the design, manufacture, and sale of precision molds and the sale of plastic products. Its stated after-sales services include online technical support, mold maintenance guidance, and spare parts supply.
