INDUSTRY PROFILES

Introduction

This Industry Profile is one of a series briefly describing small or medium-sized industries. The Profiles provide basic information for starting manufacturing plants in developing nations. Specifically, they provide general plant descriptions, financial, and technical factors fox their operation, and sources of information and expertise. The series is intended to be useful in determining whether the industries described warrant further inquiry either to rule out or to decide upon investment. The underlying assumption of these Profiles is that the individual making use of them already has some knowledge and experience in industrial development.

Dollar values are listed only for machinery and equipment costs, and are primarily based on equipment in the United States. The price does not include shipping costs or import-export taxes, which must be considered and will vary greatly from country to country. No other investment costs are included (such as land value, building rental, labor, etc. as those prices also vary. These items are mentioned to provide the investor with a general checklist of considerations for setting up a business.

IMPORTANT

These profiles should not be substituted for feasibility studies. Before an investment is made in a plant, a feasibility study should be conducted. This may require skilled economic and engineering expertise. The following illustrates the range of questions to which answers must be obtained:

* What is the extent of the present demand for the product, and how is it now being satisfied?

* Will the estimated price and quality of the product make it competitive.

* What is the marketing and distribution plan and to whom will the product be sold?

* How will the plant be financed?

* Has a realistic time schedule for construction, equipment, delivery, obtaining materials and supplies, training of personnel, and the start-up time for the plant been developed?

* How are needed materials and supplies to be procured and machinery and equipment to be maintained and repaired?

* Are trained personnel available?

* Do adequate transportation, storage, power, communication, fuel, water, and other facilities exist?

* What management controls for design, production, quality control, and other factors have been included?

* Will the industry complement or interfere with development plans for the area?

* What social, cultural, environmental, and technological considerations must be addressed regarding manufacture and use of this product?

Fully documented information responding to these and many other questions should be determined before proceeding with implementation of an industrial project.

Equipment Suppliers, Engineering Companies

The services of professional engineers are desirable in the design of industrial plants even though the proposed plant may be small. A correct design is one that provides the greatest economy in the investment of funds and establishes the basis of operation that will be most profitable in the beginning and will also be capable of expansion without expensive alteration.

Professional engineers who specialize in industrial design can be found be referring to the published cards in various engineering magazines. They may also be reached through their national organizations.

Manufacturers of industrial equipment employ engineers familiar with the design and installation of their specialized products. These manufacturers are usually willing to give prospective customers the benefit of technical advice by those engineers in determining the suitability of their equipment in any proposed project.

VITA

Volunteers in Technical Assistance (VITA) is a private, non-profit, volunteer organization engaged in international development. Through its varied activities and services, VITA fosters self-sufficiency by promoting increased economic productivity. Supported by a volunteer roster of over 5,000 experts in a wide variety of fields, VITA is able to provide high quality technical information to requesters. This information is increasingly conveyed through low-cost advanced communication technologies, including terrestrial packet radio and low-earth-orbiting satellite. VITA also implements both long- and short-term projects to promote enterprise development an transfer technology.

GENERAL DESCRIPTION

The Product

The product is hardwood, kiln dried and machined to dimensions required by customers. Products of the mill may include cut-to-size rectangular pieces, edge-glued panels, moldings, turnings, cabinet parts, stair treads and risers, and shaped pieces, as well as by-products useful as fuel. Most customers are manufacturers of furniture, cabinetwork, doorframes and windowframes, toys, boxes, and decorative or display items. Products vary greatly among mills; some mills may produce finished articles for the consumer market.

The Facility

To illustrate costs, this Profile describes a medium-sized mill operating with one shift that produces 4,500 cubic meters of dimension hardwood per year. Some information is also provided for a mill twice as large. The annual production for a mill in a developing country is often less than 2,000 cu m; some are designed to produce more than 20,000 cu m. Some hardwood mills produce sawn lumber, which is the raw material; some grow timber to replenish this valuable natural resource.

The raw material and the product are heavy and bulky. Thus, the mill should be located on a railroad or waterway, or near an all-weather road that can be used for motor transport.

GENERAL EVALUATION

Prospects for development are good if the source of rough lumber is far from the mill's customers (assembly plants) and the transportation facilities are average. Then the customers profit from reduced shipping costs from the mill, because kiln drying and sawing to size usually involve a weight loss of up to two thirds. In addition, the lumber is delivered in needed sizes, kiln dried and ready for use; users need not stockpile lumber or dispose of large amounts of waste. Prospects are favorable if the cost of labor near the source of raw material is low relative to its cost in the customers' area.

Outlook

Economic. The market should be analyzed to determine whether existing conditions will produce sufficient sales in the target area. The economic outlook is good if the trend is toward the use of dimension hardwood by assembly plants to take advantage of lower labor or transportation costs.

Technical

Sound, nonbrittle hardwood must be available. In tropical areas, the characteristics of some wood species may have to be learned by experience. The mill manager must be thoroughly experienced. Once the plant has started operating, the manager and three skilled workers should be able to train the other workers and reach full production in several months. A mill can readily. meet its training and management requirements under conditions that prevail in most developing countries.

Manufacturing Equipment Flexibility

The machinery is versatile. A few machines can produce a wide range of lumber sizes and a variety of products for which there is a market.

Knowledge Base

Personnel should have or acquire knowledge of species characteristics; operation and maintenance of woodworking machinery, including saw sharpening and tensioning; wood-moisture relationships (drying); storage, packing, and shipping; and, especially, plant safety and quality control at every stage.

Quality Control

Product concerns include size tolerances, moisture content of the wood (measured with a meter), and consistent visual quality to meet customer specifications. Process concerns include giving high priority to preventive maintenance of tools and machinery, and to proper wood handling, stacking, storing, and shipping.

Constraints and Limitations

Marketing, the key to success, must be budgeted into the operations from the start; otherwise the enterprise will fail. Efficient utilization of capacity is also important to success.

Formal training in mill safety and attention to hazardous conditions are essential to guard against serious accidents and injuries. Hazards include inadequate preventive maintenance of tools, improper disposal of wastes, inhalation of sawdust and of formaldehyde used in glues, insufficient protection of eyes and ears, and incorrect handling of lumber and sharp tools.

MARKET ASPECTS

Users

A market potential exists only where there is developed manufacturing sector or an export prospect. Marketing effort is usually needed in order to reach builders, as well as assemblers and marketers of furniture, cabinetwork, and other items that use wood components.

Suppliers

Sawmills produce the raw material, which is sawn lumber that may be air dried or kiln dried. Knowledgeable persons from the dimension plant must be prepared to visit the sawmill at the time of purchase. The cost of raw lumber transport to the dimension mill helps to set the selling price of the finished dimension product. All needed materials and supplies are expected to be available locally. If the rough-sawn lumber has been dried before delivery, it is then cut to size.

Sales Channels and Methods

Sales generally are directly to manufacturing industries according to their specifications of dimensions, moisture content, and degree of machining. Such standard items as moldings may be marketed through brokers.

Geographic Extent of Market

Markets, including export markets, depend on strong consumer acceptance of the processed species of wood.

Competition

For several decades there has been a slow increase in the substitution of softwood for hardwood for many applications. The substitution has not overtaken the absolute growth in hardwood demand. Success in meeting all forms of competition requires, the following capabilities:

  • Delivering commercial volumes of product. + Delivering quality to meet commercial specifications. + Meeting delivery dates. + Maintaining competitive prices. + Customer service.

PRODUCTION AND PLANT REQUIREMENTS

Requirements are given for a medium plant. If planning for a larger plant, merely scale up the version of the medium plant. However, equipment, supplies, and labor requirements of the larger plant vary greatly according to the degree of product diversification.
