Many readers may be unaware of exactly how a retread is manufactured, so in order to avoid the plethora of misinformation about retreading, in our third article on this subject we focus on the manufacturing process.
Understanding Hot Cure vs Cold Cure Retreading Methods
There are, in fact, two distinct methods of manufacturing retreaded, these being known as hot cure or mould cure on the one hand, and cold cure or precure on the other. The difference between the two processes lies in how the tyres are built and cured, so the beginning of the process is the same for both processes.
Using casings are first collected, sorted by size and inspected for damage to make sure the tyres can be safely retreaded. This is generally carried out by trained personnel, who inspect the tyre visually. However, tyres may also be checked by tyre testing equipment such as nailhole detectors or shearography equipment.
The old tread is then removed from the casing using a buffing machine. This process reveals minor injuries which are repaired using air buffers, buffout tools, stone grinders and brushes in a process known as skiving. The hole created during this process are then filled in with rubber using a hand held extruder gun……

轮胎翻新过程和MS224认证的重要性
许多读者可能不知道翻胎是如何制成的。为了避免过多有关轮胎翻新的错误信息,我们将在以轮胎翻新为主题的第三篇文章中,重点关注翻胎的制造过程。
市面上有两种不同的轮胎翻新方法,一种被称为热翻或模具硫化,另一种则被称为冷翻或预硫化翻新。这两种工艺的区别在于轮胎的制造和硫化方式,然而它们最初的流程是相同的。
首先是收集使用过的胎体,按尺寸分类并检查是否有损坏,以确保轮胎可以安全地被翻新。这一般由经过培训的人员目视检查轮胎。然而,轮胎也可以通过轮胎测试设备,如钉孔检测器或散斑轮胎无损检测仪进行检查。
接着使用轮胎打磨机除掉胎体上的旧胎面。在这个过程中将发现轻微的损伤,可以使用空气缓冲器、打磨工具、手摩机(stone grinders)和刷子在称为刮削的过程中修复轮胎。然后,在该过程中将橡胶填充在磨损处,并以手持式挤胶枪涂敷胶水……
