Enzan Grey Machine Tool Accessories Manufacturing Co., Ltd. specializing in the production of plastic towline, plastic towline their threading the form can be divided into: 1. The bridge engineering plastic towline 2 semi-closed engineering plastic towline Hermetic engineering plastic drag chain engineering plastic towline their stringing specifications size generally inner diameter height standard parameters} can be divided into: 7 series, 10 series, 15 series, 18 series, 20 series, 25 series, 30 series, 35 series, 45 series, 55 series, 56 series, 62 series, 80 series. structure (1) of the plastic towline the towline shape like tanks chain, unit link, link between rotating freely. (2) of the same series towline inner, outer same pitch towline inner width, the bend radius R can have a different choice. (3) unit chain around the chain plate and the upper and lower cover, towline each section can be opened, easy assembly and disassembly without threading, open the cover to cable, tubing, trachea, water pipes into the towline . (4) other shim chain space separated as needed. Plastic towline basic parameters 1) material: reinforced nylon, with high pressure and tensile load, good toughness, high elasticity and abrasion resistance, flame retardant, high and low temperature performance is stable, can be used in outdoor, nylon content determines how much the the towline use of strength and wear resistance as well as the size of the noise up and running. The nylon content ranging from 5% to 17%, but over, but 19%. Are generally about 30% of the content. (2) resistance to: oil, salt, and acid, alkali capacity. (3) The operating speed and acceleration (specific speed, acceleration depending on operating conditions may be). (4) operating life. (5) to see the structure is not only in the mechanics sent back role, but look appearance.
