The purpose of packaging is to protect the product from damage during storage and transportation. Packaging sometimes also acts as a decoration product to promote sales.
category
According to the packaging object, there are two types of parts packaging and machine packaging. Components are packaged to protect the accuracy of the product, and are easy to assemble and install on site.
Packaging in accordance with the form of internal packaging and external packaging. Products with simple structure can be packaged at one time, and some components only need partial protection. Packaging should meet the requirements of various users, such as meeting the needs of end consumers or the needs of collaboration plants; the need for immediate sales or inventory reserves; domestic sales or foreign trade needs. If you need to take a long time to sea, you must pay more attention to moisture, rust and corrosion.
skills requirement
Mechanical products must be inspected before packaging and ensure a complete set. Packaging technology requirements are mainly rust, moisture, pressure, impact resistance, suitable for storage, transportation and sales.
Anti-rust and moisture-proof requirements: General use of anti-rust oil coating products, precision products and components of the packaging selection strippable plastic sealed or sealed nitrogen. Some products can be packed in cartons with corrosion inhibitors and box liners. The agent is gasified at room temperature to form a rust-proof film on the surface of metal parts. In a high humidity environment, the strength and other properties of the packaging material tend to deteriorate and reduce the rust-proof effect. At this time, the product packaging is required to be partially or completely protected from moisture, and a desiccant such as silica gel, aluminum paste, molecular sieve and plastic is reasonably used. Moisture-proof material.
Pressure resistance and impact resistance requirements: The packaged product should be able to withstand a certain pressure and impact, the need to properly design the liner, rubber, spring, rubber - spring combination, foam plastic and so on. Special protective measures can be taken for the finished surface of the product, such as machine tool guides. In-situ foaming plastic (injected into the packing box with a small amount of chemicals and inflated into blister-like plastic within seconds) has good impact resistance and crush resistance. Outer packaging generally uses pre-prepared containers, boxes, cans, barrels, etc., or grid frames, crates, etc., and has good pressure resistance and impact resistance. The commonly used materials are: low moisture wood and steel. , particle board, hard fiberboard, reinforced corrugated paper, etc., and require to be recycled as much as possible on the premise of guaranteeing the quality of the package, and repeated use to reduce packaging costs.
Product storage and transportation requirements: Generally, the external dimensions of the packaging of a single product or group of products should meet the transportation unitization requirements, such as the dimensions specified for containers, trays, and goods. The packing box should have good loading and unloading conditions, meet the loading and unloading operation requirements, and be stacked in the normal environment, which should help improve the utilization of vehicles and warehouses, and improve and improve the efficiency of transportation operations. Container transport is conducive to intermodal transport and is a commonly used form of international trade. When packaging heavy machinery products, the maximum length, width, height and weight allowed in the transportation shall be taken into consideration, and the requirements for the center of gravity of the product, the inertial impact of starting and braking, its fixing method and supporting vehicles shall be specified. In order to meet the storage and transportation requirements, relevant tests should generally be conducted on the product packaging, such as waterproof, sealing, heat sealing test; horizontal impact, vertical drop, rolling vibration test; temperature, humidity, atmospheric corrosion test, etc., to ensure product packaging the quality of.
