Product Description



Manufacturing Process

Rubber Gate Seals Are Manufactured By Two Manufacturing Processes Viz., Extrusion And Moulding.

Extrusion:

Extrusion Is The Cheapest Method Of Manufacture Of Rubber Gate Seals. Expensive Moulds Are Not Required. However Close Tolerances Are Difficult To Maintain. Maintaining Uniform Cross Section Throughout The Length Of The Gate Seal Is Difficult To Achieve Thereby, Non Uniform Pre‐Compression Of The Gate Seals Is Observed. Cladded Gate Seals Cannot Be Manufactured By This Process.

Moulding:

Rubber Gate Seals Are Manufactured In Moulds Whereby A Uniform Cross Section Through Out The Length Of The Gate Seal Is Attained. Close Tolerances Can Be Achieved By This Process. There Is Better Control Over The Quality And Size Of The Gate Seal.

Shapes

Rubber Gate Seals Are Available In The Widest Range Of Shapes. Since Every Irrigation / Hydroelectric Project Has Its Own Design Requirements If The Shape Required Does Not Fall In The Existing Range Gate Seals Of Special Sections As Per The Customer S Specifications Are Also Manufactured.
