This site holds 1,406 manufacturing records. Every figure below is counted from them — not estimated, not modelled, and not sourced from an industry report. What follows is a description of the index, which is a different thing from a description of Malaysian manufacturing. The gap between those two is itself worth a section, and it comes at the end.
The geography is not where you would guess
Selangor holds 424 records, 30% of everything here. That part is unsurprising. The rest of the ranking is:
| State | Records |
|---|---|
| Selangor | 424 |
| Perak | 236 |
| Melaka | 227 |
| Kuala Lumpur | 206 |
| Johor | 70 |
| Penang | 64 |
Perak second and Melaka third is not the usual story. At city level the concentration is sharper still: Shah Alam (238), Ipoh (214), Kuala Lumpur (193) and Melaka (130) hold 775 records between them — 55% of the index in four towns.
Ipoh in particular tends to be left out of sourcing conversations that begin and end in the Klang Valley. On the evidence here that is a mistake, or at least an omission worth checking before you assume the supplier base sits where the highway does.
Category weight
Records can sit under more than one category, so these do not sum to 1,406.
| Category | Records |
|---|---|
| OEM & Contract Manufacturing | 507 |
| Electronics & Semiconductor | 217 |
| Food & Beverage Manufacturing | 143 |
| Packaging | 120 |
| Metal Fabrication | 109 |
| Plastics & Rubber | 90 |
| Chemicals & Pharmaceutical | 81 |
| Industrial Supply | 81 |
OEM and contract work is the centre of gravity by a wide margin — a third of the index, and more than twice the next category. That shape says something about who lists on public directories: firms that take outside orders have a reason to be findable, and firms running a single owned product line often do not.
A further 499 records — 35% — are filed under more than one industry vertical. These are businesses that do not sit cleanly inside manufacturing at all: a metal fabricator that also takes construction contracts, an equipment dealer that also assembles. Treating “manufacturer” as a clean category is convenient and slightly false.
How much public record there is to read
| Signal | Records | Share |
|---|---|---|
| Phone number | 1,345 | 96% |
| Google rating | 1,326 | 94% |
| Photograph | 1,154 | 82% |
| Opening hours | 1,182 | 84% |
| Website | 985 | 70% |
Nearly every record has a phone number. Only seven in ten have a website. If your shortlisting process starts by opening company websites, you are discarding 421 manufacturers before you have learned anything about them — and in this trade a missing website correlates with age and word-of-mouth trade, not with incompetence.
Review depth is thinner than consumer-facing categories would lead you to expect:
| Google reviews | Records |
|---|---|
| None | 80 |
| 1–4 | 462 |
| 5–19 | 412 |
| 20–99 | 317 |
| 100+ | 135 |
542 records — 39% — carry fewer than five reviews. Across the whole index there are 70,024 reviews and the mean rating among rated records is 4.43. That average is high enough to be nearly useless as a filter, which is the normal state of affairs for B2B review data and the reason this site ranks by weight of record rather than by star rating alone.
Opening hours as an operational tell
1,182 records publish opening hours, and the pattern splits three ways:
- 591 close exactly one day a week — the six-day operation that dominates Malaysian light industry
- 433 run Monday to Friday only
- 146 are open all seven days
A Monday-to-Friday schedule on a manufacturing record often means the address is an office or a trading arm rather than a production floor. It is not proof, but it is a cheap question to ask before you drive out to a site visit.
Where this index is wrong
Penang holds 64 records here, sixth by state. Within the electronics category Penang has 18 records against Selangor’s 69.
Anyone who knows Malaysian manufacturing will recognise that as wrong about the country. Penang’s electronics base is one of the densest in Southeast Asia. What it is not is listed. That base is concentrated in multinational plants inside free industrial zones — facilities that have no reason to maintain a Google Business Profile, take no walk-in enquiries, and do their supplier discovery through channels no public directory touches.
So the honest reading of this index is: it is a good map of the Malaysian manufacturers who want to be found by buyers who search, and a poor map of the ones who do not need to be. Those are different populations. This site is useful for the first and should not be mistaken for a census of the second.
Every figure above is recomputed from the records on each build, so if the numbers here and the numbers on the category pages ever disagree, the category pages are right and this post is stale.
