HISTORY OF FEDERAL MOGUL

Escort is a creation of Nanda Brothers with contraction vision committed

and determined. The Escorts group under the dynamics leadership of Mr. Nanda

(Chairman&M.D.) is a professionally managed multi product organization. The

Escorts group was founded at Lahore Pakistan 17th October 1944 as an agency

house-the Escorts (agents) Ltd. It came in to being with a vision that was nurtured

by Mr. Hari Nanda, Yudi Nanda, & C.K. Hazari. In infancy he suffered a severe

blow because of partition of India in 1947.

How ever the founder members shifted their operations to New Delhi and in sort he steered the concern to a place of reorganization, which is crystal clear performance. After partition in 1947 Nanda brothers continued the agency for electrical products for westing house and in mean time in undertaking another agency for heavy machinery also manufactured by westing house, in 1949 following the devaluation of rupee the company found that their agency is not working up to mark they found that government was laying much emphasis on major irrigation and industrial projects after independence.

Garbing the opportunity-Escort took an agency for heavy machinery from various countries like U.S.A., U.K, Germany, Japan, & Poland. During this time ESCORTS (agents) LTD was formed. Yudi Nanda looked after the second company, which imported & sold (M.F.) tractors in India with fraternity of 22,000 employees, 20 manufacturing plants & a turn over exceeding Rs.30 billions, the Escort group today ranks among the top industrial giants in the country a persistent annual growth rate 27% of the past decade. It is the 5th largest Engg. Company among both public & private companies.

According to economic times the Escorts is ranked among 7th in sales & 5th in

profit while amongst Engg. Companies, it is ranked 4th in sales and 2nd in profit. In

1954, the company got the incorporation certificates from the govt. of India. It

decided to branch into manufacturing & collaborated with Goetze Werke of

Germany to manufacture world-class pistons in India, which it felt the need of

quality if pistons to complement the Goetze ring it joined hands with Mahle of

Germany. For four decades Mahle pistons and Goetze rings remained undisputed

leaders in OEM and after market segments the demands for tractors was increasing

fast and the company decided to set up tractor manufacturing plant at Faridabad.

GOETZE (INDIA) LTD.

Goetze (I) Limited, Bahadurgarh was set up in 1954 with the collaboration of M/S

Goetze Werke, Germany, which started its production of piston rings for

automobile industry in 1957.

Considering the need of complete piston assembly ESCORTS LTD. ventured

into manufacturing of pistons in 1958 with the collaboration of M/S Mahle GmbH,

Germany, which delivered the Indian automobile industry its piston in 1960.

ESCORTS entered in collaboration with M/S SUKO GmbH, Germany, for

piston pins in 1967 and manufacturing started in 1968.To meet the increasing

demand of market, in 1977 a parallel unit to manufacture pistons & piston pins was

set up in Bangalore.

Technological leadership matched with innovated thinking has made Escorts

and Goetze products to enjoy a high degree of customer confidence and are the first

choice of discerning customer for application ranging from bi- wheeler to battle

tanks.

From 1st October 1996, ESCORTS LIMITED entered into joint venture with

M/S Mahle GmbH, Germany with the formation of new company, ESCORTS

MAHLE LIMITED.

In 1998, Goetze also became the part of federal mogul, a well-known group

of U.S.A. In June 2000, both Escorts Mahle Limited and Goetze have become

QS 9000 certified companies.

Following items are manufactured at Patiala plant of Escorts:

a) Aluminium pistons

b) Piston pins

c) Piston rings

d) Chrome plated rings

e) Moly rings

f) Cylinder liners

g) Light metal cylinder heads for motorcycles

PROJECT:IMPROVEMENTS IN LINE-7 TO INCREASE PRODUCTIVITY

INTODUCTION OF DRAWBACK 1: LINE 7 COMPRISES OF A 6 INDEX MACHINE ON WHICH 6 PROCESSES CAN BE DONE SIMULTANEOUSLY.THIS IS A REALLY EFFICIENT MACHINE WHICH CAN INCREASE THE PRODUCTIVITY TO A LARGE EXTENT.FOLLOWING PROCESSES CAN BE DONE ON THIS MACHINE SIMULTANEOUSLY:

1. ROUGH BORING2. FINISHED BORING3. CIRCLIP GROOVING4. ROLLOING5. FINISH CIRCLIP GROOVING6. CLEANING OF CHIPS

BUT IN LINE 7 ONLY 3 PROCESSES ARE DONE ON THIS MACHINE.ONLY ROUGH BORING, FINISHED BORING AND CIRCLIP GROOVING IS DONE ON THIS MACHINE.THIS IS A BIG DRAWBACK BECAUSE PRODUCTIVITY SUFFERS DUE TO IT. CAUSE AND EFFECT IS DISCUSSED BELOW:

CAUSE: 3 PROCESSES ARE TAKING PLACE ON THIS MACHINE. WHEREAS 6 PROCESSES SIMULTANEOUSLY CAN BE DONE ON IT.

EFFECTS:

1. TIME WASTE: EACH PISTON WHICH IS PLACED ON THIS MACHINE HAS TO GO WAIT ON THIS MACHIINE FOR A MUCH MORE TIME THEN IT SHOULD BE THERE.ONLY 3 PROCESSES ARE DONE ON THE PISTON BUT STILL IT HAS TO WAIT FOR APPROX. 2 MINUTES ON THE MACHINE.IT HAS TO WAIT FOR APPROX. 1 MINUTE EXTRA ON THE MACHINE FOR ITS TURN TO BE REMOVED FROM THE MACHINE.THIS REDUCES THE PRODUCTIVITY.

2. LENGTH OF THE LINE HAS INCREASED BECAUSE CIRCLIP GROOVING, ROLLING AND FINISHING HAS TO BE DONE ON OTHER MACHINES.

3. INCREASED LABOUR FORCE REQUIRED FOR CARRYING OUT ABOVE MENTIONED THREE PROCESSES SEPERATELY.

4. PRODUCTIVITY REDUCES.

5. COST INCREASES BECAUSE NEW MACHINES ARE TO BE USED FOR CARRYING OUT ROLLING, CIRCLIP GROOVING AND FINISHING.

HOW TO IMPROVE:

1. ALL THE ABOVE MENTIONED 6 PROCESSES SHOULD BE DONE ON THIS MACHINE. THE MACHINE SHOULD BE REPAIRED AND WHERE EVER IMPROVEMENT IS REQUIRED SHOULD BE DONE.

ADVANTAGES ON IMPROVING:

1. INREASE IN PRODUCTIVITY.2. COST REDUCTION3. TIME SAVED4. LENGTH OF LINE REDUCES

INTRODUCTION OF DRAWBACK 2: LINE-7 IS A RELATIVELY SMOOTH LINE WITH VERY LESS SCRAP.MOST OF THE SCRAP WHICH TAKES PLACE IN IT IS DUE TO ONE SINGLE FACTOR.IT IS DUE TO THE WRONG SEAT MAKING AND CENTRING.SEAT MAKING AND CENTRING IS DONE ON THE KD MACHINE.IF SOME STEPS ARE TAKEN TO IMPROVE THE CENTRING AND SEAT MAKING THEN IT IS OBVIOUS THAT SCRAP WILL REDUCE BY A LARGE EXTENT.IF CENTRING AND SEAT MAKING IS NOT PROPER THEN REST OF THE PROCESSES ARE ALSO NOT PROPERLY DONE.RESOURCES ARE WASTED ON SCRAP PISTONS BECAUSE INSPECTION IS DONE IN THE END.

CAUSE:

1. WRONG PROGRAMMING OF THE MACHINE.2. IMPROPER CASTING DONE IN THE FOUNDARY SHOP.2. TOOL GETS BLUNT AFTER SOME TIME.

EFFECT:

1. AMOUNT OF SCRAP INCREASES.2. TIME IS WASTED ON DOING THE NEXT PROCESSES ON THE PISTON.3. MATERIAL IS WASTED.4. RESOURCES LIKE TOOLS AND HUMAN ATTENTION ARE WASTED ON THE SCRAP PISTONS.

HOW TO IMPROVE:

1. INSPECTION SHOULD BE DONE IMMEDIATELY AFTER THE PROCESS OF CENTRING AND SEAT MAKING IS OVER SO THAT THE SCRAP IS SEPERATED FROM OTHER PISTONS, IN THIS WAY RESOURCES WILL BE SAVED.

2. CHANGING THE TOOLS REGULARLY.

3. INSPECTION SHOULD BE CARRIED AFTER THE CASTING IS DONE SO THAT SCRAP IS SEPERATED THERE AND THEN.

4. PROPER PROGRAMMING OF THE MACHINE SHOULD BE DONE.


1. SCRAP REDUCTION.2. TIME WASTAGE STOPPED3. MATERIAL WASTAGE REDUCED.4. RESOURCES SAVED.

IMPROVEMENT IN LINE-4:

INTODUCTION OF DRAWBACK 1: IN LINE 4 A MAJOR REASON FOR THE SCRAP IS THE MISSING CAST IRON RING. THE PISTON MADE IN THIS LINE HAS AN ADDITIONAL CAST IRON RING ADDED TO IT TO IMPROVE ITS PHYSICAL PROPERTIES LIKE HARDNESS AND LONG LIFE.SOMETIMES THIS CAST IRON RING IS ABSENT IN THE PISTON WHICH RESULTS IN THE SCRAP.DUE TO WHICH MATERIAL IS WASTED.THE MISSING CAST IRON RING IS DETECTED ONLY AFTER A COUPLE OF PROCESSES ARE ALREADY DONE ON THE PISTON.THEREFORE IT ALSO RESULTS IN WASTAGE OF TIME AND RESOURCES.

CAUSE:

1. HUMAN ERROR IN FOUNDARY SHOP: SOMETIMES THE OPERATOR FORGEATS TO PUT THE CAST IRON RONG INTO THE MOULD DURING CASTING.

2. SHIFTING MISTAKE IN FOUNDARY SHOP.

EFFECT:

1. TIME WASTAGE.2. MATERIAL WASTAGE DUE TO SCRAP3. DECREASE IN PRODUCTIVITY4. RESOURCES WASTED.

HOW TO IMPROVE:

1. INSPECTION SHOULD BE DONE BEFORE THE FIRST PROCESS OF TURNING IS CARRIED OUT.2. HUMAN ERRORS IN THE FOUNDARY SHOP SHOULD BE REDUCED.


1. SCRAP REDUCTION2. INCREASE IN PRODUCTIVITY3. MATERIAL WASTAGE REDUCES4. RESOURCES ARE SAVED.5. TOOL LIFE MORE.
