Who you are buying from

Six companies. One plastic manufacturer.

Alcami is a Thai-owned enterprise made up of six companies operating four locations in three countries — Thailand, the Philippines and Singapore. We have designed and manufactured plastic molds, parts and casings since 2001.

In Thailand that means two plants: our flagship hub in Prachinburi, equipped for both cleanroom and industrial production, and our Rayong site on the Eastern Seaboard, home to Alcami Industries and Alcami Extrusion.

We work across electronics, healthcare, automotive and food — the industries where a supplier gets audited, and where being able to answer for every step of the process matters more than being the cheapest quote in the inbox.

What that gets you

One supplier, not five

Sheet, tooling, forming or molding, washing, assembly, testing, storage and delivery all sit inside the group — so there is one contract, one schedule and one company answerable for the result.

Certified and documented

ISO 9001, ISO 14001 and ISO 22000, cleanroom production and an in-house test lab — with certificate copies supplied for your supplier qualification file on request.

25 years of doing it

Manufacturing plastics in Thailand since 2001, for brands that qualify their suppliers properly — with the process documentation and traceability that comes with that.

Vertically integrated

From raw resin to your loading dock.

Most plastic manufacturers buy in sheet, buy in tooling and subcontract washing or assembly. We own those steps — which is why a change to your part is a conversation on our floor rather than a chain of purchase orders.

Our own extrusion lineSheet made in-house
  • We extrude our own sheetCo-extrusion lines feeding a single die, so we can run multilayer ABA, AB or BA structures — including ESD properties and recycled content.
  • We build our own moldsMold design, CAM programming and CNC machining in-house — plus in-house CNC knife bending for forming blades.
  • We form and we moldThermoforming and injection molding under the same roof, so the process recommendation is based on your part — not on what we happen to own.
  • We wash, assemble and testOur own DI water plant, spray and ultrasonic washing, heat and ultrasonic welding, and a test lab for UV, drop, vibration, salt spray, ESD and CMM measurement.
  • We store it and we ship itOur own warehousing and domestic transport, plus sourcing and trading — so shipping and storage are not your problem to solve.
What we manufacture

Everything the part needs, in one group.

Two production processes, supported by the upstream and downstream services that usually mean a second and third supplier.

Plastic thermoforming

Vacuum and pressure forming for trays, housings, panels and covers — larger parts, faster and more affordable tooling.

Who we make it for

Industries that audit their suppliers.

Electronics

Casings, housings, ESD trays and carrier-tape sheet — washed, cleanliness-tested and packed for clean assembly lines.

Healthcare & laboratory

Medical-grade components and device trays produced in cleanroom conditions, DI washed and sealed for controlled environments.

Automotive & industrial

Panels, covers, technical components and handling trays, tested for UV, weathering, vibration and salt spray in our own lab.

Food

Food-contact parts and packaging backed by ISO 22000 food-safety certification and cleanroom production where the spec calls for it.

Consumer products

Housings, casings and durable everyday parts — molded or formed, finished, assembled and packed ready for retail or distribution.

Material handling

Dunnage, KLT inserts and automation trays that hold tolerance where a line's throughput depends on the part arriving square.

Supplier qualification

Built to pass your audit.

The things a procurement or quality team asks a plastic manufacturer before a first purchase order — answered up front.

ISO 9001 · 14001 · 22000

Quality, environmental and food-safety management systems, certified and maintained. Certificate copies are supplied for your supplier file on request.

Cleanroom production

Forming and molding in Class 10,000 / ISO 7 cleanrooms, with washing and packing under cleanroom conditions for parts that must arrive clean.

In-house test lab

UV chamber, weatherability, drop, vibration, salt spray, ESD and CMM measurement — plus LPC, FTIR and IC cleanliness testing, all under our roof.

Ultra-pure DI water

Our own deionized water plant — 16 MΩ resistivity, filtration to 0.1 micron, feeding spray and ultrasonic washing lines.

Traceable in-house chain

Because sheet, tooling, production, washing and testing are ours, the process record for your part comes from one system, not five subcontractors.

ISO 14001 in practice

Efficient material use, in-process regrind, and bio-based, biodegradable or recycled grades when your project can take them — we will suggest the options.

Why manufacture in Thailand

A short supply chain to almost anywhere.

Buyers comparing plastic manufacturers in Thailand tend to weigh the same three things: how close the plant sits to a port, whether the duty paperwork gets filed and who they will be talking to.

01

On the Eastern Seaboard

Our Rayong site sits in the Eastern Seaboard Industrial Estate, with logistics connectivity to Bangkok and to Laem Chabang, Thailand's main deep-sea port.

02

Duty paperwork handled

Where your market qualifies for preferential import duty, we can file the certificate of origin — FORM D, FORM E or FORM AI — on your behalf.

03

A team you can talk to

Our people work in English and Thai, and our sourcing office adds Chinese — with quote requests answered within 1 business day.

Concept to first delivery

Scraperite

A line of plastic razor blades and holders for surfaces where metal would cause damage. After its 2019 rebrand, Scraperite chose Alcami as its turnkey manufacturer and moved production out of China — first delivery in 34 weeks, and seven products inside a year.

Customs clearances per day

Consolidated inbound supply

A white-goods multinational assembling in a Thai free trade zone was processing around 30 customs clearances a day from local suppliers. Consolidating inbound deliveries through our warehouse cut that to two or three.

Where we operate

Two Thai plants, one standard.

~16,400m²
Factory floor across our Thai plants

The two plants do different jobs. Prachinburi runs thermoforming, injection molding, DI washing and CNC machining. Rayong runs sheet extrusion and film conversion, and holds finished stock in our own warehouses. Which site builds your part follows from the process it needs.

FAQ

Manufacturing with Alcami, answered.

Still have a question about your part or project? Ask our team →

Which plastic manufacturing processes does Alcami run in-house?

Thermoforming and injection molding are our two production processes, and both are supported in-house: we extrude our own sheet, design and CNC-machine our own molds, then finish with DI washing, assembly, welding and testing. CNC machining, film conversion, warehousing and transport round out the group, so one supplier covers the part from raw material to delivered pallet.

Thermoforming or injection molding — which should I choose?

Injection molding suits small, precise parts at high volumes; thermoforming suits larger parts and faster, cheaper tooling. Because we run both, we recommend the process that genuinely fits your part rather than the one we happen to have free capacity on. Send the drawing and we will tell you which way we would go, and why.

Do you make your own tooling?

Yes. Mold design, CAM programming and CNC machining all happen on our own floor, on our own equipment, by our own engineers — including the CNC knife bending we use to make thermoforming blades. When a first article needs a correction it becomes a job on our shop floor rather than a purchase order to another country.

Which materials do you work with?

Standard grades include PS/HIPS, PP, HDPE, PET/APET, PC, POM, PA and PMMA, plus TPU for overmolded parts, and we extrude PS, PP and HDPE sheet ourselves. We also offer bio-based, biodegradable and recycled grades, and our engineers will suggest options that lower the environmental load of your project.

Are you certified, and can I have copies for my supplier file?

Yes. The group is certified to ISO 9001 for quality, ISO 14001 for environment and ISO 22000 for food safety, and cleanroom production and our own test lab sit behind those certificates rather than alongside them. Tell us what your qualification pack needs and we will send the certificate copies with it.

Can you manufacture medical, food-contact or electronics parts?

Yes. We mold and form in Class 10,000 / ISO 7 cleanrooms, wash parts with ultra-pure deionized water from our own DI plant, and can double-seal or vacuum-pack them for controlled environments. ISO 22000 covers food-contact work, and our in-house lab handles cleanliness and ESD testing for electronics.

What is your minimum order quantity?

MOQ is assessed per project. A promotional item, an electronics casing and a medical tray sit at very different volumes, and the process we would choose changes the answer again. Send the part and your target annual volume and we will quote against it.

Can you help with import duty and shipping from Thailand?

Yes. We can apply for FORM D, FORM E and FORM AI certificates of origin on your behalf so you can claim preferential import duty where your country qualifies, and we run our own warehousing and domestic transport, so parts arrive at your forwarder or your door rather than only at our loading bay.

How do I start, and how quickly will I hear back?

Send a 3D CAD file or a drawing with your material, tolerances and annual volume. We reply to quote requests within 1 business day, usually with a budgetary quotation or the questions we need answered to produce one.
