Packing & Delivery
Packaging:
BRM can packing the products with sea or air standards, such as carton, PP bag, wooden case. We can offer OEM service as a professional chinese supplier.
Step 1. The goods were well wrapped in plastic to keep surface perfect.
Step 2. Then they're put in suitable grid in carton and surrounded by copious amounts of soft foam for additional protection.
Step 3. These cartons are packed in firm crates against any shipping-induced trauma.

FAQ
1. What is MIM technology?
MIM (Metal Injection Molding) is a manufacturing technology that combines the shape making complexity of Plastic Injection Molding with the material flexibility of Powder Metallurgy.
2. Is the metal melted in mould during the injection process for the MIM parts?
No. During injection process, only the binder is melted in order to make the metal powders to flow like liquid material. Upon cooling the binders solidify giving the part strength for handling which is called 'Green part'. And green part must be subsequently sintered which can get high density and required mechanical properties. We call it 'Brwon part'.
3. What is the difference between MIM process and Conventional PM parts process?
Conventional PM uses high, uniaxially applied pressure to coarse metal powders in a die set to produce moderately complex components. Typically, no further densification is gained during the sintering process. Densities achieved by this method are typically in the range of 80-90% of theoretical which limit the physical properties that can be achieved for the given alloy. MIM parts are not limited in shape complexity due to the flexibility of the injection molding process. The fine metal powders used - combine with higher sintering temperatures to allow MIM to achieve near full density in the final article approximately near to 99%. It allows MIM parts to have similar properties as given alloy.
4. Will the metal injection molding parts shrink during removal of binders?
No, the size of metal injection parts will be not changed in the debinding process. However, in order to achieve near full density, the part will undergo a size change of up to 20% in sintering process.
5. Why use Metal Injection Molding technology (MIM)?
1). MIM parts (Metal injection molding parts) have an significant advantage in producing small, highly complex metal components. While conventional technologies such as PM, machining or casting can't produce it or its cost is very high.

2). Part weight is 1~100g.
3). Part thinckness is thin and need high strength which PM and precision casting can't manufacture.
4). MIM can process those metal parts which PM can't achieve better strength and casting can't meet higher tolerance.
