Why Matching Dimensions Is Not Enough When Replacing Vacuum Suction Cups Two vacuum suction cups with the same outside dimensions may have different holding and positioning performance. Matching diameter or length and width is only the beginning of replacement selection. Effective suction area, lip geometry, material, stiffness, working height and the conditions behind the supplier’s capacity rating also matter. In EUROTECH’s […]
A normal vacuum reading does not prove that a suction cup has enough resistance to sliding. The gauge indicates pressure at its measurement point. Glass can still move if the effective suction area is too small, the contact surface has lost grip, or acceleration and machining forces exceed the available holding capacity. In EUROTECH’s glass-handling experience, cup sizing and the condition […]
APPLICATION INSIGHT · EUROTECH VACUUM TECHNOLOGIES Suction Cup Marks with Covers: Check Cup Size and Vacuum Level Suction cup marks can still appear on glass after protective covers are installed. A cover helps reduce direct contact between the suction cup material and the workpiece, but dust, concentrated contact loads and small movements can still affect the surface. When marks remain, […]
How to Measure a Replacement Glass Conveyor Roller When a conveyor roller becomes worn, cut, cracked, or damaged on a glass processing line, identifying the correct replacement is not always as simple as measuring its outside diameter. A replacement roller must match the existing conveyor mechanically while also providing suitable support and contact with the glass. For most replacement inquiries, […]
How Quick-Change Glass Conveyor Rollers Reduce Maintenance Downtime In automated glass processing, even a relatively small wear component can become a major maintenance issue when replacing it requires extensive machine disassembly. Conveyor rollers are a good example. Glass conveyor rollers operate continuously across loading, transfer, washing, processing and production areas. Over time, roller surfaces can become worn, cut or damaged. […]
Por que é que as ventosas a vácuo incham, endurecem ou racham? Quando uma ventosa industrial a vácuo fica inchada, dura ou rachada, substituí-la pelo mesmo modelo pode restabelecer a produção temporariamente. No entanto, se as condições de funcionamento permanecerem inalteradas, o problema pode voltar a ocorrer. O primeiro passo é identificar o que mudou na ventosa e a que foi exposta. […]
Vacuum Suction Cups for Hot Plastic Parts: Material Selection Guide Selecting vacuum suction cups for hot plastic parts requires more than checking a material’s maximum temperature. The cup must establish a seal, support the workpiece during movement and release it reliably. At the same time, the plastic component may still be warm, relatively flexible or sensitive to contact marks. For […]
NBR vs HNBR vs FKM Vacuum Suction Cups: How to Choose Choosing between NBR, HNBR and FKM vacuum suction cups starts with understanding what the suction cup actually encounters: the workpiece surface, contact temperature, oils or chemicals, handling motion and production cycle. NBR is a common choice for general industrial handling. HNBR can be considered when improved resistance to heat […]
Suction Cup Covers vs. Non-Marking Suction Cups for Glass Handling Suction cup covers and non-marking suction cups address surface quality in different ways. A cover adds a separate contact layer over a suitable cup. A non-marking cup uses a material compound intended to reduce traces during direct contact. The right choice depends on the surface, the cause of the marks […]
A redução das marcas deixadas pelas ventosas constitui, acima de tudo, uma melhoria da qualidade, mas o seu impacto pode ir muito além da aparência do produto. Na fabricação de vidro, cada operação de limpeza adicional, cada processo de retrabalho ou cada produto rejeitado requer recursos que, de outra forma, poderiam ter sido evitados. Isto significa que a melhoria da qualidade do manuseamento também pode contribuir para uma maior eficiência na utilização dos recursos e para um menor consumo de energia ao longo de todo o processo de produção. O sistema de ventosas MTC da euroTECH […]
