CLIFF™ Electronic Components Inc.

Introduction

We produce a versatile range of knobs designed to enhance the appearance and functionality of any equipment to which they are fitted. Our control knobs are made to high standards of finish in order to satisfy our customers most exacting requirements.

All models are moulded molded in black nylon, ABS or PP. Some models can be supplied in white or grey colours.gray colors. Other custom made colourscolors can be produced, subject to a reasonable order quantity as setup charges may be required. Some models can accept optional diamond spun or coloured colored caps. Marker dots are standard on models as indicated. The standard dot or line position is opposite the set screw or 'D' flat.

Other variants are possible subject to agreement. Please refer to the shaft size table for details.

Collet fitting using our low cost plastic collet system is available for our K9 to K12 series.

Two colour, color, moulded molded models K85M, K87MA, K87MB are suitable for mixing consoles. They combine good looks and ultimate low cost. Some models are available with a rubber soft-touch finish.

Applications requiring similar style knobs of various sizes are well catered for in our range of models.

When ordering, please specify quantity, model, colour, color, fixing, lines or dots and shaft size. If in doubt, please refer to our sales office. For example : K6C / black / SF / Marker dot / ¼" or K9 / black / marker line / 6mm splined shaft.

Typical Shaft Details

Custom Control Knobs

Where our standard designs do not suit your requirements we can produce knobs to your own designs. Sometimes we are able to modify existing tooling and avoid the need to make new full moulds. molds.

Our two colour color moulds molds can be adapted for custom designs without the need to make a full mould, within certain size constraints. Custom designs can be achieved at moderate tooling cost; usually about 50% of the cost of a full mould. mold. An eight-impression, complete, two colour color knob mould mold will cost at least £20,000. By incorporating new designs into the existing moulds, molds, the tooling cost can be reduced to between £7,000 and £10,000. Tooling of new models can be amortized quickly or may justify making new designs for smaller production runs. Actual tooling costs will depend on the complexity of the parts.

We have a number of semi custom parts which are available for use by our customers. Generally, full custom models are only available to the original user. Semi custom parts are usually produced by incorporating one or more mould mold cavities into the moulds molds used for standard products. Tooling costs for semi custom parts can be quite low; £50 to £350 for a custom shaft fitting; £750 to £3000 for a new cavity design. Actual costs will depend on the mould mold being adapted.

Injection moulding molding of two or more different kinds of plastic can give elegant solutions to many engineering design problems. In particular, the combination of hard plastic with rubber-like materials is used more often nowadays. Also the combination of opaque and clear materials is frequently used.

Knobs and buttons can be produced in almost any colour, color, from ABS, nylon, Polypropylene, Acetal etc. They can be made to fit any size of shaft. New models are produced using our ISO9001/2 approved design and production facility.

Initial information needed for a custom design is as follows: design and dimensions, material, colour, color, annual quantity, delivery date required. Please feel free to discuss these items with our sales department.
