2. PURPOSE

 

2.1 Designed for Preventing Joint gauge unbalance, and maintaining joint ....tensile strength.

2.2 Effects on automobile inner tubes on joint part ;

(1) Decrease in the repairs caused joint bare.(productivity improvement).

(2) Improving looking quality and making out tube unbalance problem.

(3) Reducing an article of consumption cost.

.Lessening motor operating time. 111111111111111111111111111111111111111111111111

.Reducing Freon gas for cooling.111111111111111111111111111111111111111111111111

(4) Saving orginal cost from decreasing the disqualifications


3.Problem on technical development and method of ..improvement

(1) Causing many loss because of cooling joint part,

(2) The fatal factor- in the automobile inner tube manufacturing process, improving joint ....tensile strength is very important point.

4. A result of development after the complement

Classification

Before improvement

After improvement

The efforts after improvement

1. The decrease in .the inferior goods  

.Per weight:159 ton .per one year .Cost:318,000,000 .won per one year  

.Per weight: 110 ton .per one year  

. Per weight :40 ton per one ..year
. Reduced cost:98,000,000 won ..per one year

2. The reduction in .the repairs

.Per weight: 339ton .by one year

. Per weight: 40ton .per one year

 .Reduced weight: 229ton per ..one year
.Rework cost reduction: .240,000,000won per a year   

3. The reduction in .electric power .cost .and gas cost

.Electric power cost: .7,560,000won
.Gas cost: 4,800,000 .won

.Electric power .cost: no cost
.Gas cost: no cost

.Electric power cost: .12,360,000won reduction.
.Gas cost: 4,800,000 won

4. Improvement of .Tire balance and .looking quality

.When tire rotates, .the .balance of tire .can .not maintained ,or .the shape of tire .often is transformed

.Settling all problem

.When tire rotates, the balance .of tire can not maintained ,or .the shape of tire often is .transformed
