定义Definition	滚塑又称旋转成型，是一种用于成型中空零件的工艺。 Rotational molding, or rotomolding, is a manufacturing technique used for creating hollow plastic products.	吹塑是一种热塑性加工工艺，利用气压将塑料坯料吹成中空产品。 Blow molding is a process used to produce hollow plastic parts by inflating a heated plastic blank inside a mold.
工艺流程Process Steps	模具加料 → 模具加热旋转滚动 → 模具冷却开模 → 取出成品。Mold loading with LLDPE→ Heating and rotation of the mold→ Cooling → removal of the finished product.	熔融塑料挤出 → 型坯吹胀 → 模具冷却成型 → 取出成品。Melting and extruding plastic→Inflating the plastic into mold cavities→Cooling and ejection of the part
关键特点Key Characteristics	模具简单、结构灵活，可用于大型或复杂形状的制造。Allows creating durable, large, and complex-shaped products.	效率高，适用中小型容器的批量生产，制造壁厚均匀的产品。Suitable for high-volume production and uniform wall thickness.
特点ADVANTAGES	结构坚固，耐冲击。厚度均匀，可制造大尺寸产品。制作复杂形状、纹理丰富的产品。保温性能好，适宜长时间保存食物或药品。Durability: Extremely rugged and impact-resistant, ideal for rough use. Uniform Wall Thickness: Ensures consistent insulation and strength throughout the cooler. Customizable Sizes and Shapes: Can be manufactured in various sizes, including very large ones.	轻便灵活，常用于小型保温箱。生产速度快，适合大批量生产。壁厚均匀，但在尺寸和复杂形状上有所限制。成本低，适用于一般家庭或短时间使用。 Lightweight: Easier to carry and transport due to thinner walls. Cost-Effective: Lower production costs, making the product more affordable. High Production Speed: Faster cycle times suitable for mass production.
应用场景USAGE	Insulation for long-term or large items, such as cold chain transportation and extended outdoor ice storage.用于长时间或大型物品保温，如冷链运输、户外长时间冰封。	用于家用、露营以及短期保温需求，如便携式午餐箱、短途旅行箱。Designed for household, camping, and short-term insulation needs, such as portable lunch boxes and travel coolers.
