Lesieur创立于1908年，主要生产和销售各种植物油、酱汁和调味料，其创新产品特别关注口感、质量、营养和可持续性。2015年，这家隶属于Avril集团的公司，对其旗下生产厂启动了现代化转型计划。其中，古德克尔克工厂作为其欧洲超大规模的食用油生产商，在过去三年里，专项投入2000万欧元，并已收到良好成效。
这家历史悠久的Lesieur工厂，年均装瓶量为1.7亿升，工厂一直寻求提高产品包装质量，而且希望降低由于吹瓶和灌装中心各自独立而带来的生产调度上的限制。另外，工厂产能安排上主要依托七条装瓶生产线来实现，其中包括几条小型低速生产线。
“我们决定投资C联机吹瓶生产方案。现在，我们只有五条生产线，但得益于西得乐的高速解决方案，我们提高了总体产能。此外，这还显著降低了我们的生产成本”。
此次转型主要通过投资三套西得乐/斯拉克Combi一体机，该设备集吹瓶、灌装和封盖功能于一体，可生产0.5升/1升到2升/3升规格的包装产品，生产速度从1.5万瓶/小时到3万瓶/小时。Lesieur项目经理Francis Arulraj表示：“我们决定投资C联机吹瓶生产方案。现在，我们只有五条生产线，但得益于西得乐的高速解决方案，我们提高了总体产能。此外，这还显著降低了我们的生产成本”。
利用新Combi一体机加热和吹瓶技术，可确保始终如一的瓶体完好性和质量。这种技术上的改变，不仅提高了生产质量，而且工艺流程上也更符合人体工学。西得乐设备占地面积非常小；因此该企业无需再专门布置传送带和走道，更方便操作员日常工作。在生产换型时，整个生产团队不仅可以轻松完成，还满足了生产和调整换型需求。例如，模具换型时间更短、也更容易，有效减少了生产停机时间。生产经理Denis Trelhu表示：“在西得乐包装团队的鼎力支持下，我们还提高了生产线的包装适用范围。经过合理规划，瓶型数量从22种变为14种，由于采用了相同外径，我们现在可以通过更精简的方式处理生产计划，同时仍然能向客户提供不同的瓶型方案。”
With the new Combis, the heating and blowing technologies ensure consistency in bottle integrity. This technological change has improved not only quality, but also ergonomics. Sidel’s equipment takes up very little floor space; thus, it has helped the company remove conveyors and walkways and make the operators’ daily work easier. When it comes to format changeovers, not only are they easy enough to be done by the entire production team, but they also meet production and adaptability needs. The mould changeover time, for instance, is shorter and easier, which lowers production downtime. “We have also optimised our line’s availability thanks to the support of the Sidel packaging team. By rationalising the number of bottle formats from 22 to 14, thanks to a common outer diameter, we now have a much leaner way to approach our production schedule, while still being able to propose different shapes to our customers,” states Denis Trelhu, Production Manager.
Ensuring a sustainable future with light-weighted rPET bottles
Whether transparent or opaque, PET is a material of choice when it comes to bottling edible oil, since the bottles can be formed into specific shapes. As a leading PET solution provider, Sidel has really contributed to Lesieur’s sustainability vision. “We have actually reduced the weight of our preforms. We are now able to produce bottles between 16-18 grams with up to 100% rPET,” comments Denis. Not only the packaging, but also the production line helped Lesieur pursuing the goals from its sustainable development chart. By virtue of an optimised oven and lamps, the overall electrical consumption of the blower has been lowered. Moreover, blowing pressures have been greatly reduced, which leads to a decrease in energy consumption for the compressor fleet.
“We have developed an excellent partnership with two historic suppliers, Sidel and Serac, who have proven their expertise in the oil bottling field, while also leveraging the experience of the technicians who have been on site throughout the project. With this three-sided partnership, we are sure to take a big step forward,” concludes Christophe Lance, Plant Manager.
