Shaoxing Sking Technical Appliance Co., Ltd. GCG-7003 304 STAINLESS STEEL BLADE&CUP AND PLASTIC BASE COFFEE GRINDER A coffee grinder with a 304 stainless steel blade and cup and a plastic base refers to a coffee grinder that incorporates a stainless steel blade and grinding cup, while the base or housing of the grinder is made of plastic. Here's an overview of these materials: 304 Stainless Steel Blade: The blade inside the grinder is made of 304 stainless steel, which is a common and widely used grade of stainless steel. It is known for its excellent corrosion resistance, durability, and ability to maintain its sharpness over time. The stainless steel blade is responsible for grinding the coffee beans into the desired consistency. 304 Stainless Steel Cup: The grinding cup, sometimes referred to as the grinding chamber or container, is also made of 304 stainless steel. This material ensures that the cup is resistant to rust, easy to clean, and safe for food preparation. The stainless steel cup is where you place the coffee beans for grinding. Plastic Base: The base or housing of the coffee grinder is made of plastic. Plastic is a lightweight and durable material commonly used in the construction of household appliances. The plastic base provides stability and support for the grinder, while also keeping it lightweight and easy to move around. Combining stainless steel components with a plastic base is a common design choice for coffee grinders. Stainless steel ensures the grinding components are durable and resistant to wear, while plastic offers cost-effectiveness, portability, and ease of manufacturing. When using a coffee grinder with a 304 stainless steel blade and cup and a plastic base, ensure that the stainless steel components are detachable and easy to clean. GCG-603 COFFEE GRINDER WITH UNIQUE SAFETY LOCK SWITCH A coffee grinder with a unique safety lock switch is designed to provide an extra layer of safety during operation. The specific details of the safety lock switch may vary depending on the grinder model, but here's a general idea of how it works: Normal operation mode: When the grinder is not in use, the safety lock switch is typically in the "unlocked" position, allowing the grinder to be turned on and used normally. Locking the grinder: To engage the safety lock feature, you usually need to twist or press a specific part of the grinder, such as a knob or button, while simultaneously turning or pressing the main power switch. This action secures the grinder in the "locked" position. Activation process: With the grinder locked, attempting to turn it on or activate the grinding mechanism won't work. This prevents accidental or unauthorized use, especially in households with children or pets. Unlocking the grinder: To unlock the grinder and make it operational again, you typically need to reverse the process. This usually involves twisting or pressing the designated part of the grinder while simultaneously turning or pressing the main power switch. The safety lock switch provides an additional safeguard against accidental grinding, ensuring that the grinder is only activated when intentionally unlocked. This feature can be particularly useful to prevent mishaps, especially if the grinder is within reach of children or if there is a risk of unintentional activation.
