1. 1. Quality and Appearance

   The quality and appearance of car bumpers is of great importance as they are a prominent feature of a vehicle's exterior. To meet the required standards, bumpers must have a smooth surface, consistent color, appropriate weight, and the correct size and shape. Ensuring that these standards are met is essential for creating a safe and reliable vehicle.

   
   The CLF TWII series of car bumper injection molding machines is designed to meet these strict requirements. The machines use a five-point outward toggle design to maintain the shape of the framework, as well as a PP high-mixing screw to achieve a smooth finish. Additionally, the use of a multi-loop system allows for increased productivity without sacrificing quality. By utilizing these techniques, the TWII series is able to produce bumpers that meet the necessary standards for smoothness, uniformity, weight, and size.
   

2. 2. Light-weight

   Nowadays, the automotive industry has been trending towards more light-weight parts. The large car bumper is one of the auto parts that is getting light-weight than before. However, the bumpers are still big in size, so they need to be made with large injection machines which have large space for mold. Bigger mold with smaller clamping force becomes a requirement that manufacturers need while producing car bumper. Due to the shape and size, bumper production requires an injection molding machine that features wide platen design. Therefore, many OEMs prefer buying large injection molding equipment with small clamping forces or exchanging smaller screw/injection units, which could save money.
   
   With more and more demands showing up, CLF has developed the TWII injection molding machine series specially for car bumpers. It has a wide platen design, which can fit wider/bigger mold, and is suitable for wide, deep, or long mold products. For car bumper manufacturers, the TWII series can match their mold size without spending much more money to buy a bigger injection molding machine. Besides, the TWII also features an ultra-long mold opening stroke for more rapid and smooth mold opening and closing. Through this special design, our TWII can achieve high accuracy with faster clamping speed.

3. 3. Energy saving

   Injection molding machines typically consume a significant amount of energy, particularly when they are operating at full capacity. Energy-efficient car bumper injection molding machines can help to reduce energy consumption and lower operating costs. Reducing energy consumption can also have a positive impact on the environment. Our TWII uses a servo energy saving system instead of a traditional motor system, which could save 50% of energy. And with an electric charging system, we could save an extra 25% on energy. Moreover, with special barrel heating elements.

Types of auto car bumper making machines

An auto car bumper forming machine refers to manufacturing equipment used to create bumper shapes and designs. These machines can create bumpers from various materials, including metal, plastic, and composites. They often utilize processes such as shaping, stamping, molding, welding, and assembly to produce the final product.

Here's a breakdown of some categories of car bumper manufacturing machines:

• Metal bumper forming machines: This category has several machines, each catering to a unique aspect of bumper creation. The metal stamping press stands out, utilizing powerful presses to mold metal into specific shapes. Coupled with this is the die-making process, where specialized molds are crafted to assist the stamping press achieve desired bumper designs. Next are metal shaping and welding machines. These machines are tasked with refining metals into accurate bumper shapes, as well as soldering seams and joints to enhance structural integrity. Lastly, the metal bending machine also plays a key role in metal bumper manufacturing by bending the metals into specific shapes and designs.
• Plastic bumper forming machines: Plastic injection molding machines are pivotal in the production of plastic bumpers. These specialized machines inject plastic materials into pre-designed molds, allowing them to cool and harden into the final bumper shape. This process not only creates lightweight bumpers but also maintains the same level of quality. In addition to the injection molding machines, there are also 3D printers for bumpers. Advanced manufacturing technology like 3D printing allows for the creation of custom plastic bumpers through additive manufacturing, layer by layer printing. This method enables precise and complex designs to be realized easily. Finally, the CNC milling machines, which are computer numerically controlled equipment, are crucial to plastic bumper production. These machines precisely mill and cut plastic materials, including bumps, to accurately create the desired shapes and designs.
• Composite bumper forming machines: Composite bumpers combine durability and lightweight properties, making them ideal for automotive applications. The manufacturing process of composite bumpers uses numerous specialized machines. First, the extrusion lamination lines are used to create tailored composite materials by combining several fibers and plastics through extrusion and lamination processes. Next, the spray machines equally play a vital role in this process by evenly coating the automotive substrates with matrix materials. Finally, curing ovens provide the perfect temperature for solidifying and hardening the composite materials, allowing them to set properly and gain strength before further processing.
