Introduction to Vacuum Plating:

Vacuum plating mainly includes vacuum evaporation, sputtering, and ion plating. They are all used to form various metal and non-metal films on the surface of the product by distillation or sputtering under vacuum conditions, so as to achieve the effect of electroplating.

LKKER SCM currently uses mainly vacuum evaporation. Vacuum evaporation (vacuum evaporation coating) is a technology in which the evaporated material is heated by an evaporator to vaporize it under vacuum conditions, and the evaporated particle stream is directly shot to the product and deposited to form a solid film on the product.

The film material (aluminum wire) is placed in the evaporation source (tungsten wire) in the vacuum chamber. Under high vacuum conditions, the evaporation source heats up to make it evaporate. After the atoms and molecules of the film material vapor escape from the surface of the evaporation source, they are directly When it reaches the surface of the product to be plated, due to the low temperature of the product, it condenses to form a film.

In terms of the production process, LKKER SCM has expanded from a single manual electroplating line in the original Shenzhen Guanlan factory to a vacuum electroplating department integrating automatic and manual lines in the current Tangxia factory.

Introduction to Electroplating process:

Material degreasing → cover mold → clamping → dust removal → UV spraying

→UV Curing → Coating → Finishing → Baking → Inspection → Packaging

The failure of many products is attributed to a lack of knowledge in supply chain

What is the product supply chain. Many simply perceive it as logistics , transport , factory  or system.  Now we show you how LKKER SCM makes products.

The first thing that came to the mind of many at the mention of the supply chain would be logistics, transportation, loading and unloading. After a great deal of explanation, the response I got was,
“Oh, we have a new term for express delivery?”
“Well, I still don’t quite understand what supply chain is.”
 

Today, I am going to discuss with you what “supply chain” actually does. Before we begin, take a moment to picture what supply chain is to you.

First of all, what is supply chain?

Wikipedia says: In commerce, supply chain management (SCM), the management of the flow of goods and services, involves the movement and storage of raw materials, of work-in-process inventory, and of finished goods from point of origin to point of consumption. 

Don’t worry if the explanation doesn’t make any sense to you. The article I wrote today is to explain the supply chain management service of our company in simple words.

 

Let’s take a look at the 12 major production processes of a product.

When we need mobile phones, computers, remote controls, washing machines and other things that we can’t live without, we would turn to Target and Amazon. But has it occurred to you how these products are produced, put on store shelves and the e-commerce store before purchased by you?

If you dig deeper, you are getting closer to what our company is doing, in the technical term, “product supply chain”.

Before a product is produced, it will undergo 12 production processes: product definition, strategy analysis, appearance design, software and hardware R&D, mechanical design, feasibility evaluation, prototype making, supplier matching, mold design and making, pilot production, testing and certification, production and supply. After the product is launched, there are another two important processes: channel integration and product marketing.

LKKER SCM offers customers services covering the whole industry chain from product design, R&D, production and supply, to marketing, channel, capital and incubation and provides users with total solutions for innovative products

We are here to assist you materialize your ideas from concepts to physical products.

What are the specifics of these production processes?

很多产品就是死在不懂供应链的路上

From mere concept to market analysis, verification of the feasibility of product functions, then to appearance and mechanical design, hardware and software R&D by ID, MD designers, R&D and Product Manager, determination of product appearance framework, internal mechanism, and implementation of product features, followed by production of appearance prototype, functional prototype, and the verification of the feasibility of product design. Generally speaking, it is to make a model out of design drawings to see if the appearance and mechanical design are reasonable, and whether the product functions can be implemented.

很多产品就是死在不懂供应链的路上

很多产品就是死在不懂供应链的路上

Next, resource matching. To match the most suitable manufacturer who understands the product best to design mold and make products out of molds. After a product is produced, a pilot production is required to prevent mass production defects caused by materials, die sinking, and improper process control and ensure success mass production.

 很多产品就是死在不懂供应链的路上

Finally, we have to find a testing and certification company to conduct a sample inspection of product quality and to audit and evaluate the quality system of the enterprise. More generally speaking, it is to find professional quality inspectors to stamp your product to prove that your product quality is acceptable, so that users can use it with assurance.

很多产品就是死在不懂供应链的路上

 

The last but not least, the production and supply. It also poses challenges to sell (sell to whom and how to sell).
