引言 Introduction

现代轮胎制造是一个高度自动化、高精度的系统工程，一条合格的轮胎从原材料投入到成品出厂，需要经过 8 个核心工序。每个工序都有严格的工艺参数和质量控制标准，任何环节的偏差都可能影响轮胎的最终性能和安全性。对于轮胎从业者而言，掌握完整的制造流程，能够更专业地向客户解释产品生产周期、质量控制体系和性能特点，提升客户信任度。

Modern tyre manufacturing is a highly automated and high-precision systematic engineering. A qualified tyre goes through 8 core processes from raw material input to finished product delivery. Each process has strict process parameters and quality control standards, and deviations in any link may affect the final performance and safety of the tyre. For tyre trade practitioners, mastering the complete manufacturing process enables more professional explanations to customers about product production cycles, quality control systems and performance characteristics, enhancing customer trust.

本文结构：为了便于理解，我们将 8 道工序归纳为四个阶段——胶料准备 → 部件制造 → 胎体组装 → 定型与质检。沿着这条路线，你能看清一条轮胎从粉末与生胶，到可装车使用的完整变形记。

阶段一：胶料准备 Stage 1 — Compound Preparation

第一道工序：混炼 Mixing

混炼是轮胎制造的第一道工序，其核心目的是将生橡胶、炭黑、白炭黑、橡胶油、硫化剂、促进剂、防老剂等多种原料，按照精确的配方比例均匀混合，制成性能一致的橡胶胶料。混炼过程在密闭的密炼机中进行，通过高强度的机械剪切和加热作用，使各种原料充分融合，形成均质的胶料。混炼质量直接影响后续所有工序的加工性能和轮胎的最终物理性能。

Mixing is the first process in tyre manufacturing. Its core purpose is to uniformly mix various raw materials such as raw rubber, carbon black, silica, rubber oil, curing agents, accelerators and antidegradants according to precise formula ratios to produce rubber compounds with consistent properties. The mixing process is carried out in a closed Banbury mixer. Through high-intensity mechanical shearing and heating, various raw materials are fully integrated to form a homogeneous compound. The quality of mixing directly affects the processability of all subsequent processes and the final physical properties of the tyre.

一句话理解：这道工序就像"和面"——所有原料在这里被打成一块性质均匀的"面"，后续一切部件都由它塑造。

阶段二：部件制造 Stage 2 — Component Manufacturing

第二道工序：挤出 Extrusion

挤出工序用于生产具有特定截面形状的轮胎半成品部件。混合好的胶料被送入挤出机，通过螺杆的推送和挤压作用，经过特定形状的模头挤出，形成胎面、胎侧、三角胶（胎圈填充胶）等连续的橡胶型材。挤出后的部件经过冷却、定长裁断后，存放备用。挤出过程需要严格控制温度、压力和挤出速度，以确保部件的尺寸精度和表面质量。

The extrusion process is used to produce semi-finished tyre components with specific cross-sectional shapes. The mixed compound is fed into an extruder, pushed and squeezed by a screw, and extruded through a die of specific shape to form continuous rubber profiles such as treads, sidewalls and bead fillers. The extruded components are cooled, cut to length and stored for later use. The extrusion process requires strict control of temperature, pressure and extrusion speed to ensure the dimensional accuracy and surface quality of the components.

第三道工序：胎圈制作 Bead Making

胎圈是轮胎与轮毂连接的关键部件，其作用是将轮胎牢固地固定在轮毂上，并传递车辆的驱动力和制动力。胎圈制作首先将高强度镀黄铜钢丝捻制成钢丝帘线，然后将多根钢丝帘线并排排列，缠绕成圆形的钢丝圈。钢丝圈表面包覆橡胶，再与胎圈包布、三角胶等部件组合，形成完整的胎圈组件。胎圈的强度和尺寸精度直接影响轮胎的安装安全性和行驶稳定性。

The bead is a key component connecting the tyre to the rim. Its function is to firmly fix the tyre on the rim and transmit the driving and braking forces of the vehicle. Bead making first twists high-strength brass-plated steel wires into steel cords, then arranges multiple steel cords side by side and winds them into circular bead rings. The bead rings are coated with rubber, then combined with bead chafers, bead fillers and other components to form complete bead assemblies. The strength and dimensional accuracy of the beads directly affect the installation safety and driving stability of the tyre.

胎圈是轮胎的"卡扣"——它决定了轮胎能不能牢牢抓住轮毂。

第四道工序：压延 Calendering

压延工序的核心是给纺织帘线（聚酯、尼龙）和钢丝帘线均匀地覆上一层薄橡胶，制成帘布。帘线是轮胎的骨架材料，承担着轮胎的主要负载，而橡胶的作用是将帘线粘合在一起，并保护帘线免受腐蚀和磨损。压延过程在大型压延机上进行，帘线通过加热的辊筒之间，橡胶被压入帘线的缝隙中，形成两面覆胶的帘布。压延质量直接影响轮胎的结构强度和耐久性。

The core of the calendering process is to uniformly coat a thin layer of rubber onto textile cords (polyester, nylon) and steel cords to produce cord fabrics. Cords are the framework materials of tyres, bearing the main load of the tyre, while rubber functions to bond the cords together and protect them from corrosion and wear. The calendering process is carried out on large calenders. The cords pass between heated rolls, and rubber is pressed into the gaps between the cords to form cord fabrics coated with rubber on both sides. The quality of calendering directly affects the structural strength and durability of the tyre.

帘布是轮胎的"钢筋"——压延就是给钢筋裹上一层保护与粘合的橡胶。

第五道工序：裁断 Cutting

压延制成的帘布需要按照轮胎设计要求，裁切成特定角度和尺寸的帘布片。裁断角度和尺寸精度直接影响轮胎的结构强度和均匀性。不同部位的帘布需要不同的裁断角度，例如胎体帘布通常采用 90 度裁断，而带束层帘布则采用小角度裁断。裁断后的帘布片需要进行拼接，形成适合轮胎成型的长度。

The cord fabrics produced by calendering need to be cut into cord fabric pieces of specific angles and sizes according to tyre design requirements. The cutting angle and dimensional accuracy directly affect the structural strength and uniformity of the tyre. Different parts of the tyre require different cutting angles. For example, body plies are usually cut at 90 degrees, while belt plies are cut at small angles. The cut cord fabric pieces are spliced to form lengths suitable for tyre building.

阶段三：胎体组装 Stage 3 — Carcass Assembly

第六道工序：成型 Building

成型是将所有轮胎半成品部件组装成生胎（Green Tyre）的过程。成型过程在轮胎成型机上进行，分为两段式成型和一段式成型两种工艺。首先在成型鼓上依次铺设内衬层、胎体帘布、胎圈、胎侧等部件，然后反包胎体帘布包裹胎圈，形成轮胎的基本形状。接着在胎体上铺设带束层和胎面，完成生胎的组装。生胎是未硫化的轮胎半成品，依靠橡胶自身的粘性临时固定在一起。

Building is the process of assembling all semi-finished tyre components into a green tyre. The building process is carried out on tyre building machines, and there are two types of processes: two-stage building and one-stage building. First, the inner liner, body plies, beads and sidewalls are laid sequentially on the building drum, then the body plies are turned up to wrap the beads, forming the basic shape of the tyre. Next, the belts and tread are applied on the body to complete the assembly of the green tyre. A green tyre is an unvulcanized semi-finished tyre, temporarily held together by the inherent tackiness of the rubber.

到了这一步，轮胎已经"长"出完整的样子了——但还只是靠橡胶粘性固定的"生胎"，一加热就会散，所以必须进入下一步。

阶段四：定型与质检 Stage 4 — Curing & Quality Control

第七道工序：硫化 Curing

硫化是轮胎制造中最关键的工序，通过高温高压使生橡胶发生化学交联反应，将塑性的生胶转变为弹性的熟胶，同时赋予轮胎最终的形状和花纹。生胎被装入硫化机的金属模具中，内部充入高温高压的蒸汽或过热水，使生胎膨胀并紧贴模具内壁，形成胎面花纹和胎侧标识。

Curing is the most critical process in tyre manufacturing. Through high temperature and high pressure, it causes a chemical cross-linking reaction in the raw rubber, transforming plastic green rubber into elastic cured rubber, while giving the tyre its final shape and pattern. The green tyre is loaded into the metal mold of a curing press, and high-temperature and high-pressure steam or hot water is filled inside to expand the green tyre and press it tightly against the inner wall of the mold, forming the tread pattern and sidewall markings.

硫化工艺的核心参数：

硫化不足会导致轮胎强度不足、耐磨性差，而硫化过度则会使橡胶变硬、弹性下降。因此，必须严格控制硫化参数，确保轮胎性能达到设计要求。

Under-curing will result in insufficient tyre strength and poor wear resistance, while over-curing will make the rubber hard and reduce its elasticity. Therefore, curing parameters must be strictly controlled to ensure that tyre performance meets design requirements.

硫化是"点石成金"的一步——生橡胶在这里被彻底改变，从可塑变得有弹性、耐磨、能承重。

第八道工序：检测 Inspection

所有轮胎在出厂前都必须经过严格的质量检测，确保产品符合国家标准和客户要求。检测工序主要包括以下项目：

All tyres must undergo strict quality inspection before leaving the factory to ensure that products meet national standards and customer requirements. The inspection process mainly includes the following items:

• 外观检测 Visual Inspection：人工或通过机器视觉检查轮胎表面是否有气泡、缺胶、划伤、杂质、花纹错位等外观缺陷。
  Manually or through machine vision, inspect the tyre surface for appearance defects such as bubbles, missing rubber, scratches, impurities and pattern misalignment.

• 均匀性检测 Uniformity Test：使用轮胎均匀性试验机检测轮胎的径向力波动、侧向力波动和锥度，确保轮胎行驶平稳，避免车辆抖动。
  Use a tyre uniformity machine to detect the tyre's radial force variation, lateral force variation and conicity to ensure smooth driving and avoid vehicle vibration.

• 动平衡检测 Dynamic Balance Test：检测轮胎的质量分布均匀性，在轮胎两侧粘贴平衡块，使轮胎在旋转时保持平衡。
  Detect the uniformity of the tyre's mass distribution, and paste balance weights on both sides of the tyre to keep it balanced during rotation.

• X 射线检测 X-Ray Inspection：检测轮胎内部的钢丝帘线是否有断裂、错位、弯曲等结构缺陷，确保轮胎的结构安全。
  Detect internal structural defects such as broken, misaligned or bent steel cords to ensure the structural safety of the tyre.
