Ultra-high Molecular Weight Polyethylene Uhmw-pe / Pe 1000 Plastic Sheet For Sale

Uhmwpe Sheet Compression Molding Process

• Mold Preparation: The mold is designed to the desired shape and size of the UHMWPE sheet. 
• Powder Filling: UHMWPE powder is carefully loaded into the mold cavity. 
• Compression: The mold is placed in a compression molding press, where high pressure is applied. 
• Heating: The mold is heated to a specific temperature to facilitate the fusion of the UHMWPE particles. 
• Dwelling: The material is held under pressure and temperature for a specific duration to ensure complete consolidation. 
• Cooling: The mold is cooled, allowing the UHMWPE sheet to solidify and retain its shape. 
• Demolding: The finished UHMWPE sheet is removed from the mold.

Cut to Size

UHMW (Ultra High Molecular Weight Polyethylene)  is a common machinable plastic known for durability, versatility and cost-effectiveness as well as abrasion, impact and chemical resistances. FDA compliant natural virgin UHMW is used in applications where high levels of friction are likely to arise including conveyor guard rails, augers and wear strips, belt scrapers, chain guides, and idler rollers. Due to an extremely low coefficient of friction, its inherent lubricity minimizes heat-generating friction that tends to gradually destroy steel parts, and ensures smooth, noiseless operation.

UHMW Annealing

Annealing (stress relief) of machined or semi-finished products is recommended when dimensional stability and freedom of distortion (warping & bowing) of the finished part is desired. Annealing temperatures of 210-310° F (100-160° C) combined with slow cooling will relieve residual stresses, normally caused by non-uniform crystallization during the cooling process. Thicker parts are more subject to residual stresses, since the outside surface cools much more rapidly than the insulated core of the part or billet. Rapid cooling creates an outer shell which restricts shrinking and promotes internal stresses.

In order to properly anneal Uhmwpe the part should be heated in an oven or a liquid bath containing silicone oil or glycerine. Temperatures above 275-280° F (135-138° C), the crystalline melting range of Uhmwpe are preferred. Although heating rate is not important (20° F or 10° C/hr above 175° F or 80° C), cooling rate is critical and care must be taken to slowly reduce the oven or bath temperature at 10° F (5° C) per hour until reaching 150° F (65° C). The part should then be wrapped an insulating blanket to permit slow cooling for 24 hours.

Machined parts with narrow tolerances should only be rough machined prior to stress relief. These parts should be fixtured during the annealing process due to shrinkage. Care should be taken not to overheat the machined surface during final machining to eliminate potential distortion and dimensional change

Polyethylene 1000 / PE UHMW

UHMW (Ultra-High Molecular Weight Polyethylene) offers moderate flexibility with excellent memory properties. While not as flexible as rubber or elastomers, UHMW can flex under load and return to its original shape, making it ideal for applications requiring both impact resistance and some degree of bend without permanent deformation.

Polyethylene 1000 / UHMW Polymer is a Linear Polyethylene with a molecular weight in the range of 3,000,000 to 6,000,000. This value represents the “average molecular weight”.

Therefore, UHMW plastics have a molecular weight average 10 times that of conventional high-density polyethylene resins.

The higher molecular weight is what gives UHMW Polymers a unique combination of characteristics making it more suitable for many applications where lower molecular weight grades fail.

PE1000 is a high-performance polyethylene with product characteristics including a reduction in dust accumulation, high wear resistance and high impact strength.

The long term service temperature range of PE1000 (UHMWPE) Sheet is from 80°C to 130 °C and has a short term maximum service temperature of 150°C

 3-axis cnc Milling

The technique of CNC milling is a kind of computer-controlled milling in which a milling cutter, which is a revolving tool with a cylindrical shape, is used to remove material from a solid substrate to expose a finalized component. Milling machines controlled by a computer may be divided into two primary groups: those with three axes and those with multiple axes. Milling machines with three axes can move the cutting tool or the workpiece in all three linear directions (left to right, back and forth, and up and down), making them ideal for producing designs with less complex elements. Milling machines with four axes or more and multi-axis milling machines are the most effective tools for making plastic components with intricate geometries.
