Small batch production is the center and future of production. Industrial planning always plays an important role in the whole situation. Small batch manufacturing is the epitome of modern manufacturing technology. Small batch manufacturing not only plays a very important role in product planning decomposition, but also is a powerful tool for product information security and market promotion.

With the increasingly fierce competition in the social market and the expansion of industrial planning, all industries attach importance to industrial planning and the production of manual models. The development quality and practical role of products need to be verified by companies. Small batch hand model industry has gradually separated from the process of industrial planning, and become a relatively independent industry. With the vigorous development, many professional small batch production companies have emerged. Large planning companies and industrial planning companies have established their own small batch processing offices.

Small batch production of hand panels solves the problem of multiple exhibitions

The products produced need a small batch trial production, so that more products can participate in the exhibition. Sometimes, there will be many places in the world, each place needs a set of hand board model, so small batch rapid production can solve these problems.

There are many ways to process the hand-board model, usually according to the customer's 3D drawings. Computer Gong carving is the most commonly used processing method, followed by SLA laser rapid prototyping, which requires small batch processing to produce more products to participate in the exhibition. In some cases, there will be many exhibitions around the world, such as Shanghai, Hong Kong and Shenzhen. These are just exhibitions in China. If there are other places in the world, such as American International Exhibition, European Exposition. All of these require a set of hand-drawn samples, so small batch production can solve these problems.

In order to improve the competitive advantage of product development as we all know. But in many cases, we need to save time,which means saving the product development cycle, and strive for listing as soon as possible. Saving time is saving cost. When we make ABS hand boards, the average time is 3 to 5 days.

How to use the best method to produce high quality hand-plate model and save time and cost is an important sign to test the scale of hand-held factory. We need to find a factory that can deliver the hand-board in time and make it completely according to the design requirements. Such a handboard factory can be based on the market and it will have its own survival rules.

Production Management of Small Batch and Variety

The production mode of small batch and multi-variety is to adapt to the changing market, according to market demand, order, quality, quantity and punctual production. In the market economy, consumers tend to diversify their hobbies and pursue high-level, unique and popular commodities different from others. New products emerge in an endless stream. In order to expand market share, enterprises must adapt to this change in the market. The diversification of enterprise products has become an inevitable trend. Of course, we should see that the diversification of products and the emergence of new products will also lead to the elimination of some products before they are out of date and still have usable value. It is a great waste of social resources, and this phenomenon should arouse people's attention. Its goal is to shorten the delivery time and reduce the inventory of the production system.

1.Improve adaptability to changing demand

Small batch, single piece transmission

Multi-skilled employees

Internal Quality Assurance System of Processes

Universalization of Equipment and Fixtures

2.To expose manufacturing problems and their weaknesses

Quality failure

Equipment failure

Workload imbalance

Transfer time

3.Eliminate waste caused by improper production management and reduce production management costs

Material waiting due to improper production management

Unnecessary type change due to improper production management

Increase in indirect operations due to improper production management

4. Improve the adaptability of manufacturing to short delivery time

Eliminating Stagnation ( Information of it)

Reduce the number of intermediate products in process

Synchronization

Characteristics of small batch and multi-variety

1. Multivariate Parallel

Because the products of many enterprises are aimed at customer configuration, different products have different needs, and the resources of enterprises are in many varieties.

2. Resource Sharing

Every task in the production process needs resources, but the resources available in the actual process are very limited. For example, equipment conflicts are often encountered in the production process, which is caused by project resource sharing. Therefore, limited resources must be appropriately allocated to meet project needs.

3. Uncertainty of Order Result and Production Cycle

Because the demand of customers is unstable, and the planned nodes are inconsistent with the complete cycle of human, machine, material, method, loop, etc., the production cycle is often uncertain. The project with insufficient cycle needs more resources, which increases the difficulty of production control.

4. Variable material requirements lead to serious procurement delays

Due to the insertion or change of the order, it is difficult for external processing and procurement to reflect the order delivery time. Because of small batches and single source of goods, the supply risk is very high.

Difficulties in small batches and multi-varieties

1. Dynamic process path planning and virtual unit line deployment: emergency plug-in, equipment failure, and bottleneck drift.

2. Bottleneck identification and drift: before and during production

3. Multi-level bottleneck: assembly line bottleneck, parts virtual line bottleneck, how to coordinate coupling.

4. Buffer size: either backlog or poor anti-jamming. Production batch, and transfer batch, etc.

5. Production scheduling: We should not only consider bottlenecks, but also the impact of non-bottleneck resources.

There are also many problems in the practice of multi-variety and small-batch production mode in enterprises, such as:

It is very difficult to arrange mixed production for multi-variety and small-batch production.

If delivery is not on schedule, there are too many "fire fighting" overtime.

Orders require too much follow-up

Frequent changes in production priorities prevented the original plan from being executed

Inventories are increasing, but critical materials are often lacking

The production cycle is too long and it expands indefinitely in advance.

Multi-variety and Small-quantity Production

1.Necessity of Import

Purple: to shorten the manufacturing cycle, reduce inventory and adapt to load changes.

Conditions: shortening the preparation time, multi-frequency handling, process internal quality control, rely on improving manufacturing technology to shorten manufacturing cycle, standard operation, parts synchronous supplying mechanism (parts matching, Kanban management), flexible equipment, production plan to be divided into small batches to organize production.

The ultimate goal: balanced production: daily multi-model production + single-piece transmission production with different models mixed

2.Are all types of machines suitable for small quantity batch production?

This is not the case. Manufacturing should match the sales speed, so the market demand for large-scale or medium-batch production of models.

ABC analysis method is derived from the PQ analysis method which can distinguish the boundary.

Mode of production:

1. For mass production

1. For Medium-batch production

1. For small batch production

Because the market is changing in many directions, mass production is the reason for the increase of inventory. We should try our best to avoid this mode of production, so that we can reduce the inventory by daily production (small batch production).

Production switching of multi-varieties and small batch orders

The switching action on the production site can be divided into the following types:

Type 1: Mould, Tool, Fixture and Mould Switching

This type of switching can be seen more in mechanical processing plants and plastic injection plants, and it is also the most common example of switching action.

For example, the die of punch, injection moulding machine, lathe, drill tool replacement, etc. Therefore, it is sometimes collectively referred to as "die changing operation" or "die changing". However, this usage is easy to mislead people who are not sure about it, or beginners. They think that the switching action is limited to the switching of moulds and so on. Therefore, I think that it is more appropriate to use "switching" as a general term.

Type 2: Switching of Standard Change

For example, when computers and numerical controllers are used in precision cutting or chemical devices, once the product is changed, the setting conditions must be changed. In fact, in the whole process of "switching", adjustment is the most time-consuming and difficult part to overcome.

Type 3: Switching of parts and materials in assembly line

In the assembly line, when the product changes, the parts or materials used must follow the change. This kind of action is generally called "line-changing operation". In traditional Line-Changing operations, it's common to wait until the last product is finished before the whole production line stops to change.

As an assembly line with many assemblies, this method will cause a long time of shutdown and a great loss. In fact, if we can change the line in sequence, no matter how many stations there are on the assembly line, the loss of the change time is only cycle time of one station.

Type 4: General preparation before manufacture

It refers to the preparatory work that must be done before the start of manufacturing, such as drawing review before mechanical processing, job assignment and cleaning up after work.

Four kinds of switching actions, though different in content, result in production standstill is the same. However, most people only focus on the improvement of switching action in the first mode changing operation, while ignoring the improvement of the other three modes. In fact, the improvement of the latter three types is easy to achieve. It also saves considerable switching time

Small batch production products  is a unit of customized production and small batch production. There are many kinds of products produced in small batches, and the output of each variety is small. It needs to organize production according to the needs of users. It has the advantages of flexibility and good adaptability to the external market.

Brief overview

Owing to the wide range of batch production, it is usually divided into "mass production", "medium-batch production" and "small-batch production".

Small batch production refers to the production of special products which are basically required in small batches.

Single-piece small-batch production is a typical make-to-order (MTO), which has similar characteristics with single-piece production and is customarily called "single-piece small-batch production". Therefore, in a sense, "single piece small batch production" is more in line with the actual situation of enterprises.

It is composed of customized products (such as batch production clothing and turbines for hydroelectric power generation, etc.) and small batch production units.

Basic characteristics of mass production

Small batch production has the following characteristics:

1. Long manufacturing cycle and long ordering period.

2.Universal equipment, a large number of employees, low production efficiency and low labor productivity.

3.High cost.

4. Product quality can not be guaranteed.

Mass production refers to the continuous repetition of the manufacture of the same products in a longer period of production. Here are some characteristics of mass production: less product varieties, large product output, relatively stable production, long-term fixed to complete the same product of one or two processes in one workshop, a higher degree of specialization. Mass production manufacturing generally can has pipeline, automatic line and other advanced forms of production organization, and operating workers usually engage in regular occupation, which is conducive to improving the operational proficiency of workers and labor productivity. Mass production process can be a kind of simple production, or it can be a kind of complex production. In the enterprise and workshop of mass production, it is appropriate to take the form of object specialization to divide the production units, and layout of required various production equipment according to the process flow.
