§1What this business is
Tie bars are the strong round bars that support and align the platens of an injection moulding machine and carry the clamping force on the mould. The same kind of bar is used in die-casting, forging, pressing and pneumatic machines. The unit cuts MS bar (IS 2062 / SAE 1018) on a power hacksaw, turns and threads it on a CNC lathe, mills flats and keyways on a CNC milling machine, grinds the surface and checks dimensions with gauges. It is a precision machine shop that works to the machine maker's drawing. The DPR sells a tie bar at ₹475.
Capacity: 20,000 tie bars a year worth ₹95 L; 70% use is assumed in the first year.
§2Is it right for you?
Who it is for
A CNC machinist or tool-room owner near a cluster of plastic moulding or die-casting units.
Who it is not for
Anyone who cannot read engineering drawings or measure to microns.
Advantages
- One raw material — mild steel round bar
- Two CNC machines do most of the work
- Every injection moulding, die-casting and press machine needs tie bars and replaces broken ones
- The same shop can take other precision turning jobs
Drawbacks
- High break-even of about 66%
- Buyers are a small number of machine makers and plastic moulders
- CNC machines lose value fast — the DPR depreciates them at 20% a year
- Close tolerances mean any error is scrap
Skills you need
- CNC turning and milling
- Thread cutting and surface grinding
- Measurement with micrometers, bore and slip gauges
- Selling to machine makers and moulders
Why difficulty 3/5: A simple product, but it needs CNC skill and steady industrial customers.
§3Market
Who buys
- Injection moulding machine makers
- Die-casting, forging and press machine makers
- Plastic moulding units needing replacement tie bars
- Mould and die makers
How it sells
- Direct orders against the machine maker's drawing
- Job work for larger machine shops
- Machine spares dealers
Good to know
- The DPR's price is ₹475 a tie bar.
- The DPR notes that 'tie bar' is also the name of bars used in concrete road joints and railways, so the import figures under these steel-bar codes cover more than this product.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: EEPC India
- Confirm the 8-digit ITC(HS) line with DGFT or your customs broker before shipping.
- You need an Import Export Code (IEC) from DGFT before the first shipment.
§9Risks — where people fail
- Orders depending on a few machine makers
- Steel price changes between quotation and delivery
- Rejection for dimension or surface finish
- CNC breakdown stopping the whole shop
