Shenhua Master Rubber
Shenhua master rubber is a professional anti-fray master rubber and high-performance edge protection master rubber in the printing and packaging industry, designed to solve the problems of paper fraying, edge bursting and powder dropping during die cutting. Made of high-elasticity premium rubber material with precision extrusion process, no adhesive backing design, height must be higher than steel blade during use. This master rubber is installed on both sides of the die cutting blade. It contacts and presses the paper around the blade first during die cutting, preventing paper fibers from being lifted by the blade, forming a smooth and flat cut, completely solving the problems of burrs, edge bursting and slag dropping when die cutting thick paper, corrugated paper and special paper, significantly improving the appearance quality and cutting accuracy of die cutting products, and is an essential protective consumable for die board manufacturing in the printing and packaging industry.
Why choose the Shenhua Master Rubber
Completely Solve Fraying and Edge Bursting Problems
Specially designed for die cutting edges, close to both sides of the blade, with height higher than steel blade. It presses the paper first during die cutting, fundamentally solving the problems of burrs, edge bursting, powder dropping and slag dropping when die cutting thick paper, corrugated paper and special paper, with smooth and flat cuts.
Scientific Height Design
Standard height is higher than steel blade. It contacts the paper first and then cuts during die cutting, presses the paper fibers in advance, avoiding the blade lifting paper fibers when cutting, completely eliminating fraying and edge bursting from the source.
High Elasticity Premium Rubber Material
Adopts high-elasticity imported rubber raw materials with good resilience and small compression set, not easy to collapse after long-term use, can continuously and stably press the paper, with long-lasting protective effect.
Precise Size Control
Strict production process ensures precise dimensions and uniform thickness and height, which can perfectly fit both sides of the blade without affecting the normal cutting depth of the die cutting blade.
FAQ About Master Rubber
Q1: Why is the height of master rubber designed to be higher than steel blade?
A: This is the core design principle of master rubber: height higher than steel blade, the rubber will contact and press the paper first during die cutting, so that the paper fibers around the blade are fixed in advance, and then the blade cuts the paper, so there will be no fraying and edge bursting caused by the blade lifting paper fibers.
Q2: What materials are master rubber suitable for?
A: Shenhua master rubber is specially suitable for die cutting protection of various thick papers, corrugated papers, grey boards, special papers, laminated papers, gold cardboards, leather, EVA and other materials prone to edge bursting and fraying.
Q3: Can master rubber be used in high-speed die cutting machines?
A: Yes, Shenhua master rubber adopts high-strength formula, which can adapt to the continuous operation requirements of high-speed die cutting machines, and still maintain stable protective effect under high-speed operation.
Q4: What factors affect the service life of master rubber?
A: The service life of master rubber is mainly affected by factors such as the hardness of die cutting materials, die cutting speed and die cutting pressure. Under good operating conditions, the product can maintain stable performance.
