Core performance advantages: adapt to the harsh working conditions of machine tools
1. Super sealing and protection ability: tightly fill the gaps of key parts such as machine tool rails, spindle boxes, distribution boxes, etc., effectively blocking the intrusion of cutting fluid, iron shavings and dust, reducing the risk of wear and electrical failure of mechanical parts, and prolonging the maintenance cycle of machine tools.
2. Excellent temperature resistance and medium resistance: the temperature resistance range can reach -40℃~200℃, which can withstand local heat when the machine tool is running; at the same time, it is resistant to the corrosion of cutting oil, coolant, hydraulic oil and other industrial media, not easy to swell and age, and stable performance in long-term use.
3. High elasticity and shock absorption cushioning: With excellent elastic resilience, it can be repeatedly compressed without deformation in the opening and closing movement of the machine tool (such as protective doors and sliding tables), which can not only ensure the sealing effect, but also buffer the movement impact and reduce mechanical noise and vibration.
Product Features: Meet the actual application needs of machine tools
1. Strong customisation adaptability: It supports flexible cutting or customisation according to the size of the sealing groove of the machine tool (such as rectangular, round, D-type, etc.) and the length, perfectly matches the non-standard gaps of different models of machine tools (such as lathes, milling machines, machining centres), and solves the problem of poor adaptability of general seals.
2. Easy to install and maintain: Some products come with their own high-performance backing adhesive, which can be directly pasted and fixed by tearing off the mould paper. It is convenient to install and not easy to shift. The strip has good toughness and is not easy to tear. It can be quickly peeled off during later replacement, and no residual glue stains to pollute the surface of the machine tool.
3. Both environmental protection and durability: food-grade or industrial-grade environmental protection silicone raw materials are used, no pungent odour, and meet RoHS and other environmental protection standards to avoid harm to the workshop environment and operators; at the same time, it has strong anti-ageing and anti-ultraviolet ability, and the service life can reach 1-3 years under normal working conditions, which is far more cost-effective than ordinary rubber or sea. Cotton sealing strip.
Application value characteristics: enable the efficient operation of machine tools
1. Improve the accuracy and stability of the machine tool: through stable sealing and shock absorption, reduce the impact of external impurities on precision parts such as guide rails and screws, reduce the processing error caused by vibration, and ensure the consistency of the processing accuracy of parts.
2. Reduce the cost of comprehensive use: on the one hand, reduce the cost of machine tool maintenance and replacement of spare parts caused by sealing failure; on the other hand, by blocking the leakage of cutting fluid, save the amount of consumables and reduce the cleaning workload of the workshop.

Frequently asked questions and answers about silicone foam strips for machine tools
I. Sealing and protection issues
1. Question: The gap of the machine tool is not tightly sealed, and there is leakage of cutting fluid and intrusion of iron shavings. Is it a problem with the silicone foam strip?
Answer: Possible reasons include: the specifications of the foam strip do not match the gap (too thin leads to insufficient compression), the ageing of the strip and the loss of elasticity, and the existence of joint gaps or folds during installation. It is recommended to replace the new strip that adapts to the specifications, and use 45° splicing and compaction at the joint to ensure that there is no gap.
2. Question: After the foam strip comes into contact with the cutting fluid, there is swelling and deformation, and the sealing effect is reduced. How to solve it?
Answer: This is because ordinary silicone foam strips are used, and their oil resistance and chemical resistance are insufficient. It is necessary to replace the "special oil-resistant silicone foam strip for machine tools". This kind of product is added with oil-resistant additives, which can resist the erosion of cutting fluid and lubricating oil and avoid swelling and deformation.
II. Problems of wear and ageing
1. Question: The foam strips of the moving parts of the machine tool (such as sliding tables and protective covers) wear out too quickly and need to be replaced frequently. What should I do?
Answer: Give priority to "high wear-resistant machine tool silicone foam strip" (the surface can be reinforced); at the same time, check whether the moving parts are misaligned and stuck to avoid abnormal friction; when installing, a small amount of special grease can be applied to the contact between the foam strip and the moving surface to reduce wear.
2. Question: When the machine tool is used in a high-temperature environment (such as near the spindle and heating device) for a long time, the foam strip quickly becomes hard and brittle. What is the reason?
Answer: The upper temperature resistance of ordinary silicone foam strips is mostly 150-200℃. If the local temperature of the machine tool exceeds the tolerance value, it will accelerate ageing. It is necessary to replace the "high-temperature resistant silicone foam strip" (temperature-resistant up to 250-300℃), and try to add a heat-insulating cushion between the foam strip and the high-temperature parts.
III. Installation and adaptation issues
1. Question: The sealing groove of the machine tool is shaped (such as arc, step-shaped), and the ordinary straight foam strip cannot fit. How to deal with it?
Answer: Choose a flexible and cuttable machine tool silicone foam strip, and cut it section by section according to the shape of the sealing groove; for parts with large arcs, the foam strip can be softened and fitted with a hot air gun (40-60℃), and it can be fixed after cooling; the special-shaped joint can be fixed with silicone adhesive.
2. Question: The foam strip is easy to fall off from the sealing groove after installation, especially when the machine tool vibrates. How to fix it?
Answer: Choose a machine tool silicone foam strip with "back glue", tear off the mould paper and paste it directly into the clean and dry sealing groove; if it is back glue-free, you can evenly apply a small amount of neutral silicone adhesive in the groove (to avoid contamination of the moving parts of the machine tool), and press it for 3-5 minutes after embedding.
IV. Selection and quality issues
1. Question: How to choose a silicone foam strip with suitable hardness according to the needs of the machine tool?
Answer: Choose according to the sealing scenario: 1 Static gap sealing (such as box, cover plate): choose 40-50 Shore A hardness, taking into account sealing and installation convenience; 2 Dynamic sports sealing (such as protective cover, sliding table): choose 50-60 Shore A hardness to improve wear resistance and change resistance Shape ability; 3 High-pressure sealing (such as hydraulic station cover plate): choose 60-70 Shore A hardness to ensure that it is not extruded under high pressure.
2. Question: How to identify the quality of silicone foam strips for machine tools and avoid buying inferior products?
Answer: It can be simply judged through 3 points: 1 Look at the elasticity: it can bounce back quickly after being squeezed by hand, and there is no obvious depression residue; 2 Test strength: it is not easy to tear when stretched, and there are no obvious bubbles and impurities in the cross-section; 3 Check the performance: the supplier is required to provide oil-resistant, temperature-resistant and wear-resistant performance test reports. Poor-quality products are usually not regular The test proves that there is a pungent rubber smell.
