Injection moulding company due diligence

By the time a buyer is under a letter of intent on an injection moulding company, the questions shift from whether the plant is worth pursuing to whether everything the seller has represented actually holds up on paper and on the shop floor. Diligence in this sub-sector is narrower and more mechanical than in most small-business acquisitions, because a small number of specific findings — a disputed mould, a program on notice, a press that fails inspection — can each independently change the deal.

Reconcile the mould inventory line by line

Every mould on the floor should be checked against both the company’s own records and, wherever practical, the relevant customer’s records, because customer-owned moulds are frequently the single largest gap between what a seller believes it owns and what it can actually sell. A mould booked as a company asset that turns out to be customer property is not a paperwork nuance — it directly overstates the assets being purchased, and a buyer should treat any unreconciled mould as excluded from the deal until proven otherwise rather than assumed included.

Pull and read every material program agreement

Each long-term production program agreement needs to be read for assignability, change-of-control notice obligations and any requalification right the customer holds, because a program that looks assignable on its face can still require the customer’s active cooperation to actually survive the sale. Where a program contract is silent or ambiguous on change of control, that silence is itself a finding worth raising directly with the customer, in a controlled way, before closing rather than after.

Inspect the press fleet against its maintenance history

Maintenance records only mean something once they are checked against the physical condition of the presses they describe, and a fleet that does not match its paperwork on inspection is a common and serious finding — it usually means the plant’s stated capacity is unreliable at exactly the presses a buyer is counting on. A press requiring near-term replacement that the seller’s asking price never accounted for is not a reason to walk away by itself, but it is a number that belongs in the purchase price conversation, not a surprise absorbed silently after closing.

Confirm the environmental and resin-supply picture

Any provincial environmental or waste-handling approval tied to the site should be checked directly with the issuing ministry for its current status and the process required to reissue it to a new legal owner, since a Phase I or Phase II environmental assessment finding at the property — old coolant disposal, historical contamination — can surface at exactly this stage and materially change the deal. Resin supply agreements deserve the same scrutiny: whether price movement is contractually passed through to program customers or absorbed by the plant changes the reliability of every margin figure the buyer has already modelled.

Scrap and regrind handling is worth a specific look rather than a general mention, since a plant that has never had this reviewed for waste-diversion or environmental compliance often has other operational housekeeping that has gone unreviewed for just as long. Asking directly whether regrind ratios, scrap disposal and any waste-diversion reporting have been checked against current provincial requirements gives a buyer a concrete answer rather than an inference drawn from the rest of the plant’s condition.

Confirm workplace-safety standing and any inherited product-liability exposure

A current WSIB clearance certificate should be requested directly from WSIB rather than taken from the seller’s representation, because Ontario’s system can attach successor liability for unpaid workplace-safety premiums to the purchaser, and a gap here is a specific, quantifiable finding rather than a general compliance concern. Outside Ontario, the equivalent workers’ compensation board runs its own clearance process, and a buyer should confirm the correct provincial mechanism rather than assume Ontario’s applies.

Deal structure also changes what a buyer inherits on parts already shipped before closing: an asset purchase generally leaves product-liability exposure for pre-closing production with the selling corporation rather than the buyer, while a share purchase carries that exposure forward inside the corporate entity being acquired, which is a distinction worth confirming with counsel rather than assuming either way. Where the plant’s programs run into a regulated end product — food-contact or medical-device parts — that exposure is worth taking seriously enough to review against the deal structure specifically, not folded into a general contingent-liabilities line.

What a finding actually means once you have it

Not every finding in this sub-sector is a reason to abandon the deal, but each one changes the deal differently. A disputed mould reduces the asset base and should be reflected in price, not just noted. A program customer confirming a planned end-of-life shortly after closing is a forward-revenue problem that may call for a price adjustment, a holdback, or walking away, depending on how much of total revenue it represents. A press fleet failing inspection is a capital-expenditure problem that belongs in the numbers before close, not after. And environmental non-compliance discovered during a Phase I or Phase II assessment is the finding most likely to stall or end a deal outright, because the liability it exposes can be difficult to quantify on a short timeline.
