Shenhua Printing: Teach You 5 Steps to Identify High-Quality Die Plate Rubber Gaskets and Stay Away from Inferior Consumables Scams

Currently, the printing consumables market is filled with various products, and the quality of knife plate spring pads varies greatly. Many low-priced and low-quality products flood the market. Many printing enterprises, in an attempt to save costs, blindly purchase low-priced spring pads, which results in frequent cutting faults, a sharp decline in the yield rate, and an increase in equipment wear and tear. Eventually, the overall cost rises significantly. Shenhua Printing has been deeply involved in the field of cutting consumables for many years and teaches you to quickly distinguish between high-quality knife plate spring pads and inferior ones through 5 simple steps. This helps enterprises avoid the pitfalls of low-quality consumables and choose truly high-value products at a reasonable price.

Step 1: Observe the appearance and details

High-quality knife plate spring pads have a smooth and flat surface, uniform color, no bubbles, impurities, cracks, or missing glue, and a neat edge without frayed edges; the back adhesive layer is uniform and flat, without wrinkles, detachment, or bubbles, and the back adhesive protection film is intact, with clear product model, specifications, hardness, and production date markings. Inferior spring pads are mostly produced from recycled materials, with a rough appearance, dull and uneven color, obvious bubbles, impurities, cracks on the surface, and severely frayed edges; the back adhesive layer is uneven in thickness, prone to wrinkling and detachment, and the marking is blurry or has no marking at all.

Step 2: Feel the texture and test elasticity

Press the surface of the spring pad with your hand. High-quality spring pads have a delicate and elastic texture, and can quickly return to its original shape after being pressed; when bent with your hand, high-quality spring pads have good flexibility, and will not break when bent, and will quickly return to a flat state when released. Inferior spring pads have a rough and hard texture, or are too soft and lack elasticity, and the pressing back will be slow, even leaving obvious indentations; when bent, they are prone to breaking, or cannot return to their original state after bending, resulting in permanent deformation.

Step 3: Tear the back adhesive and test adhesion

Tear off the back adhesive protection film and touch the surface of the back adhesive. High-quality spring pads have an appropriate and uniform adhesion, a smooth feel, and no graininess; when the back adhesive is applied to a clean steel plate and pressed again after being torn off, the high-quality back adhesive can firmly stick to the steel plate, and there will be no residue of leftover adhesive when it is torn off. Inferior spring pads have either too weak adhesion, which easily detaches with a gentle pull, or too strong adhesion, which leaves a large amount of residue on the steel plate when torn off, making it difficult to clean; the surface of the back adhesive has a grainy texture, and the adhesion is uneven.

Step 4: Test hardness and compare wear resistance

Use your fingernail to press the surface of the spring pad. High-quality spring pads have a high surface hardness and do not leave scratches; when gently rubbed with sandpaper on the surface of the spring pad, high-quality spring pads have good wear resistance, and there will be no obvious chipping or wear after friction. Inferior spring pads have low surface hardness and leave obvious scratches when pressed with a fingernail; after friction, there will be a large amount of residue and peeling on the steel plate, making it difficult to clean; the surface of the back adhesive has a grainy texture, and the adhesion is uneven.

Step 5: Test usage and observe results

Apply the spring pad to the knife plate for actual production testing. High-quality spring pads have stable cutting effects, thorough cutting without connection points, no burst lines, or frayed edges, and do not collapse, warp, or shift during long-term continuous production, with a long service life. Inferior spring pads have unstable cutting effects, prone to problems such as incomplete cutting, burst lines, and frayed edges, and will collapse, warp, or shift after a few hundred uses, requiring frequent replacement, seriously affecting production efficiency and product quality.

Shenhua Printing always prioritizes quality. All knife plate spring pads use brand-new high-quality rubber substrates. From raw material entry to product exit, they undergo 12 strict quality control inspections to ensure that each roll of product meets industry standards. Shenhua Printing guarantees that all products come with quality assurance. If there are quality issues, they will be returned or exchanged without conditions, allowing enterprises to purchase with no worries.
