HR for Rubber Moulding Units: Compression Presses, Curing Times and Mould Fitters
A rubber moulding unit presses and cures compound into gaskets, seals, bushes and grommets for vehicles, appliances and industry. Hot platens, mould changes and cure timing make the press operator and mould fitter the pillars of the shop.
Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsA rubber moulding unit makes parts by loading compound into heated moulds and pressing for a set cure time. Compression, transfer and injection presses are used depending on the part. After the platens open, parts are lifted out, deflashed, inspected and packed. Compound is mixed in house or bought as strip, and a mould change on one press can take hours. Orders come from vehicle, appliance and industrial customers with drawings and tolerances. The operator loads preforms, starts the timer, opens, strips and checks, working beside hot plates and steam. The mould fitter keeps tools clean and ready. Deflashers sit at tables trimming by hand. Pay is often by press or piece. See also HR for manufacturing.

When HR is weak in rubber moulding units, you may see
- Hot platens burn new operators
- Opening the press early to make the count
- Two fitters for every press on the floor
- Deflashing is dull work on the lowest rate
- Piece rates push one man onto several presses
- New hands copy whoever stands nearby
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
Who does the work in rubber moulding units
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
- Compression press operators
- Injection and transfer press operators
- Mould fitters and mould changers
- Compound mixing and preform cutting staff
- Deflashers and trimmers
- Gauge and hardness inspectors
- Tool room fitters
- Packing and dispatch hands
- Shift supervisors
Where HR strains in rubber moulding units
Hot platens burn new operators
Hot plates, steam and heavy moulds bring burns and pinched hands, mostly in an operator's first months.
Opening the press early to make the count
An operator chasing a number may open before cure ends, giving a part that looks fine and fails at the customer.
Two fitters for every press on the floor
A mould change needs a skilled fitter, and with one or two on shift, presses stand idle waiting for them.
Deflashing is dull work on the lowest rate
Trimming flash by hand strains the eyes and pays least, so people either quit or rush it.
Piece rates push one man onto several presses
An operator running three presses loses track of the timers, and speed is rewarded over a proper cure.
New hands copy whoever stands nearby
With no written press card, a joiner picks up the neighbour's shortcuts along with the skill.

Start by checking where you stand
Before changing anything, find out what is true today. These checks take an afternoon and tell you which of the topics above to start with.
Share your requirements- Walk the presses and note any without a cure time on the card.
- Ask who changes the mould when the main fitter is on leave.
- Count deflashers who joined and left over the past quarter.
- Check last month's customer returns for any tied to under-cure.
- List burns and pinched-hand incidents logged in the past half year.
- Confirm with a qualified professional the factory registration, record-keeping, hot work and employment duties that apply to your moulding shop.
Confirm with a qualified professional. What applies to you depends on your business, your state and your arrangements, and it changes. This page describes practice. It does not state a legal position.

Questions owners ask
Print cure time on the press card, explain the failure that follows and check it on rounds. Reward passed parts instead of the raw count.
Enough that no shift waits long for a change. Read the mould change log and count how often presses stood idle.
The work is repetitive and often paid least. Better pay, rotation between tables and a clear picture of a good part all help.
It depends on the part. Set a limit, watch for missed timers and scrap, and lower the limit when scrap climbs.
Pair them with a buddy, give a short guide for each press and hold a check at the end of week one, so habits are taught on purpose.
Whether cure times are posted and followed, who stands in for the mould fitter, and how many deflashers left lately. A fair opening job is an operator induction with pay on passed parts. Scope is written down once we have talked.
