Introduction

Generally machinery in the apparelindustry continues to become more

complex, knowledge of the basics of

computers and electronics willincreasingly be an asset.

Introduction

In addition, the trends towardmanufacturing keeps changing to

achieve maximum lead time efficiency

and minimum space requirement ofmachines.

Thus machinery determination

requires interpersonal skills to workeffectively with others.

Strategic Plans

These are plans that are to beconsidered before setting up of an

apparel plant

Any apparel manufacturing firm fallsunder one of the 2 categories:

1. Large Scale firm

2. Small Scale firm

6VYSALI.R


7/25

Strategic Plans - Large scale

firm The capacity of Large scale plant will

be higher.

Generally, the machinery selection will

be highly sophisticated based on thenewer automations & objectives of the

plant

7VYSALI.R


8/25

Strategic Plans - Small scale

firm The capacity of the Small scale plant

will be comparatively less.

Moreover the capital amount invested

will also be low. Hence, the machineries adapted will

be of older version that requires more

of manual assistance & low capitation

Financial Base

Primary considerations for plantownership include the firmsinvestment plant.

Machinery cost is considered in thefollowing cost analysis:

1. Startup costs

2. Overhead costs

- Variable

- Non variable

Merchandising & Sourcing

Strategies Each plant operates with a set of

characteristics unique to its existence

There are certain reasons for the

purchase of equipments:

4. What types, weights, and thickness

of materials are to be used?

5. How much flexibility does the

equipment have?

6. What automatic features and work

aids are needed?

7. What quality level is required?15VYSALI.R

CONCLUSION

Based on the above quoted parametersthe machinery selection for a new factoryvaries accordingly.

The product characteristics such as

The material used

Styling.

Quality requirements.

Cost restrictions andDelivery deadlines also defined the

need for equipment and processing

methods . 16VYSALI.R


17/25

CONCLUSION

Product specifications also determinethe specific methods , assembly

sequences and equipment needed to

produce the products. Thus , buyers specifications also play

an important role while selection of

equipments for a product line.
